WI: Mary of Burgundy hadn't died in 1482?

So what if in 1482, Mary of Burgundy doesn't fall off her horse while hunting along with Maximilian in Flanders. How could this have changed Maximilian's political alliance by marriages and how could have this affected the situation in Burgundy and the relationships with France?
 
Maximilian and Mary were at least very fond of each other; and the position of Maximilian in the Lands of Burgundy would be better than IOTL when he became the regent for Philip, this would strengthen the central authority in Burgundy (even though that was more hurt by the death of Charles the Bold).
So the transition from the house of Valois-Burgundy to the house of Habsburg-Burgundy in 'Burgundy' would be more gradual.
They might end up with more children, which would affect marriage politics.

OTOH Maximilian would be able to (try to) marry Anne of Brittany (by proxy, never came to a church marriage), this could actually lead to not a further deterioration of the Franco-Habsburg relations. No unhappy marriage with Bianca Maria Sforza either, though given the Imperial & Habsburg interests the effects might not be too large (unless she marries a French prince instead...).

A surviving Mary the Rich would make a resolution between France and Habsburg-Burgundy more difficult, Valois-France & Valois-Orléans were the rivals of Valois Burgundy since John the Fearless was murdered (although he was implicated in the assassination of the duke of Orléans); the king of France had annexed a part of her inheritance, most notably the duchy of Burgundy (proper), which from the Burgundian perspective (not French though) should have stayed in Burgundian hands. The French kings had made it a policy to frustrate her father's endeavors; and the French had almost forced her into a French marriage, which backfired a made the Habsburg archduke Maximilian the preferred candidate.
Anyway concessions will be harder, but a compromise like IOTL still seems likely.

Also given the fact that Mary's survival doesn't affect the French-Habsburg Burgundy rivalry, the Habsburgs and the Trastamaras would still want to encircle their rival and the most powerful country of Western Europe France, so the idea behind the alliances and marriages wouldn't change much.
 
Actually, at least from what I've read and researched, the territories inherited by Mary I from Charles the Bold hadn't change, it was after her death that Maximilian made a land exchange compromise with the French kings twice.

However I mostly about what would happen with Italy since (maybe?) Hapsburg interests in the area wouldn't be so large.

Yes they did change, France occupied the duchy of Burgundy (which France saw as an appanage, the Burgundian dukes had a different opinion (tradition in Burgundy (the original dukes had the right that allowed women to inherit in the absence of men); the way king John the Good of France also became duke of Burgundy, it explicitly refused to become a part of the French Crown), Picardie, the county of Artois, Franche Comté and the county of Charolais.
This conflict will have to be resolved; a part of the foreign policy of Habsburg Burgundy will be to get these territories back (IOTL emperor Charles V still wanted his entire Burgundian inheritance back); furthermore Burgundy proper could be disputed, but France's position was legally weaker in other territories (IOTL regained) with a tradition, which allowed women to inherit in the absence of men.
Armed conflict can enable some bending of the rules, but the situation after the death of Charles the Bold will lead to a Burgundian attempt of restoration.

Well Italy will be a part of the conflict, don't forget that the head of the Habsburg dynasty (usually) became the Holy Roman Emperor and the empire has it's own traditional position and ambition in Italy, Italy (formally) was a part of the Holy Roman Empire.

Furthermore the Habsburgs had their own ambitions in Northern Italy too and Milan also brings France closer to the Austrian Hereditary Lands.
Even without the Northern Italian ambitions of France, France had another major conflict with Aragon (later 'Spain') in Southern Italty regarding the kingdom of Naples. So given the fact that Habsburg-Burgundy and Trastamara 'Spain' both have a major conflict with France and thus share a common enemy, they become natural allies.
So IMO the Habsburg intrest in Italy, especially Northern Italy, wouldn't change much.
