Yes, it would.
I tried to give some deadlines estimations a while ago :
https://www.facebook.com/TouhouPatchCenter/posts/875098309216417I think HM support would take 4 to 6 months, and ULiL support would take 1 to 3 months. From what I've seen, the most important differences between HM and ULiL are the RSA key, the slightly different file format and the hundred of anti-hack stuff. The first 2 problems will be dealt with during the ULiL static patch, and I hope 3rd one won't bother me that much.
But there is a really important point when we talk about adding HM or ULiL support in thcrap : "Due to the game's fragmented manner of loading data files, creating patches that work with [thpatch], the same way as the ones for the Team Shanghai Alice games, is quite painful" (
