I don't necessarily think that Max is incapable of Alpha moves -- as I already stated in an earlier post, I think Eric is an example of a dominant alpha gone wrong. I mean, well, most of Max's moves are boyish and pervy in-game, but there are others which I consider borderline Alpha -- washing dishes, doing tutoring, spanking his siblings, buying his family clothes. Max just hasn't figured out when to do those things so that it matters a lot -- DS didn't implement it in-game, that's why I don't harsh on Max too much.
IN SUMMARY, I don't necessarily think it's difficult to change the game to make Max more of a sensitive, considerate dom -- it just takes a bit of tweaking of some dialogues arising from the good actions he does to mean something much more beyond temporarily lifting the mood scores of Ann, Lisa and Alice.
