Other mods with H/M?

[Frofster]

I was wondering if there's any way to use any other mods with H/M. I tried to install forge, but that just crashed it. I'm going to assume that it's a no.

I would also like to know this, I tried NEI with code chicken core, but that also just crashed it. Ideally I would like to add mods like Divine RPG and Mo'Creatures, that type.
