Distortion, and its use, is a very, very subjective thing and distortion in a mix is a long way from what most people imagine.
Finding the D.I. RTs is the best way to go in BIAB.
I can't see an whole suite of single person preference RTs being developed unless that individual has amazing clout.
BEST option, aside from recording your own is reamping the DI in real time.
