Well, it sounds like you would like to eat your cake, and keep it too...
Sure, you could angle the crap out of the TOM, but the more you angle it, the narrower the string spacing becomes.
If you want to do a fanned fret guitar, there are simply some things you cannot get around.
A "special" bridge and nut, for instance...
It's like saying "I want to build a neck-through guitar, but I don't really want the wood to go all the way through..."
Well, not quite, but almost.
