Regaining the Luxembourgian Inheritance won by the Albertian branch was pretty high on the wish list of the Leopoldine branch of the Habsburgs. Regaining Hungary before Bohemia might not be be bad, Maximilian & Mary were no Vlad Bene's and had the means to enforce it, so keeping Hungary stronger in the process.Mind it, Bohemia and Hungary were different beasts at the time of PoD. Hungarian throne would be contested in 1490, as Matthias lacks legitimate heir, but in Bohemia Vladislaus already is king since 1471, Bohemia is loyal to him and Silesia, Moravia, Lusatia were easily recovered by him after Matthias' death (as was predicted in Treaty of Olomouc). So it is possible for Max to win Hungarian election in 1490 (it was possible even IOTL), but Vladislaus is going to keep Bohemia.
Still Bohemia, with their electoral vote, will be on the Habsburg-Burgundy list, unlike Poland & Lithuania....
