Okay, I know how this sounds initially. I wouldn't be surprised if its previously been brought up and shot down, but...
What if framer could frame mafia? Or even just godfather?
Think about it... there are actual strategic last-second situations in which this could work. I only play classic, so maybe that's why this seems like a good idea, but..
It would be a strategic situation where framer would have to decide: is it worth covering as a jester, or is it gonna make the gf sus? Or could it throw off town more?
Anyways, I think it would be interesting to play with invest results like that I dunno.
