The ordonannce companies were quite successful when they appeared and used properly they would likely be effective in enforcing royal power in many countries.
I was wondering if the concept of a force loyal to the King and paid by taxes to keep (or at least contain) the peace might be recognized earlier in countries other than France-Burgundy.
Not all standing troops were payed by taxes :
franc-archers, similar to what existed in England, were raised troops exempted of some taxes, until being replaced by the 1480 ordinance by
bandes which were closer to actual nationally raised troops than
compagnies.
That said, these ordinances let room for much change.
One shouldn't forget that
compagnies and
bandes were created during truces, and not during the heat of the conflicts, where mercenarized and traditional troops kept an important part : the same ordinances that created standing compagnies also re-organized feudal levies and systematized them (and these kept an important part of Early Italian Wars, for instance).
Basically, you won't have a much significant quality difference by their own existence (
compagnies and
bandes were still largely influenced by professional mercenariship) but by their political (in a situation where kingship meant military role) inclusion into armies alongside more traditional features.
Not that only French lords (Burgundy, but also Brittany, Armagnac, etc.) acknowledged it : one could mention Castillan
capitanías fof 1495, for exemple.
You really had a qualitative stepstone during the wars of Italy, where the decline of Late feudal armies began at the benefit of standing armies.
As you point out feudal rights are ingrained in society by this point and it would take something dramatic to overrule them
Ah, it's going to get semantic.
Feudal rights didn't ingrained society, because they concerned maybe 5% of the population at best. It did ingrained nobility and political rules of the kingdom, tough.
(Basically, not to confuse feudality and what we call in lack of a better term "feudal society")
Rather than rights, allow me to be more vague.
Medieval concepts were, of course, as well ingrained in society than contemporary concepts are in our own. It's how we can tell they're different societies after all : you can't just provoke something dramatic to "overrule" it, indeed.
It's important to stress that standing armies re-apperance in France (and Europe more generally) wasn't made against Late feudal armies organisation, but
alongside them on a common evolution where the royal hegemony was firmly established since the XIIth century.
Rather than some traumaticevent changing all society because reasons (which is quite weak for most of situation, IMO), an ATL that focuses on a convergent devellopment should include a smooth devellopment of standing armies out of medieval society, may have more chances at plausibility.
