I read you
Well I used to think Sforza changing the Theologicals was something to do with the Council of Florence and the main subject of the split between the Eastern and Western churches- the ongoing debate about the Filioque/Trinity. A long subject that is better read about from other sources.There is the same problem with the theory that the celestials replace the theologicals (which I think iconographically they do). There has to be more to the story, celestials pre-existing somewhere.
Now I am not so sure.
I think it is a more direct reasoning.
Humanists in their search for marrying the classical thought with Christianity, sought how God perpetually revealed himself. 'I show myself' in fact -it is called Vestigial Trinitatis Triplism is expressing the Divine or a Divinity in a threefold way. Classical Litrature has The Horai- the Seasons or the Charites or Gratiae of Splendour, Mirth and Good Cheer- there are many more like Neoplatorism of Thought, Soul and The One etc etc. Christianity also took this ancient allegorical way with the Gifts of God or the three Gifts of Grace = Faith, Hope and Charity. It was used in a reciprocal way- God revealed himself freely Sun, Moon and Stars and with our Gifts of the Theologicals- we reveal ourselves freely- but even more for Milan was this idea of Rulership and Divine right and dynasty, as an echo
of this more ancient Tripilism- Father Mother and Children or the ancient idea of the function of Three states- Sovereign/King, Protector(Mother and Military), Producer...
Or it just could be a reminder for card players to show their hand at the end of the game
