I don't see why not dude. If its meant to model the real amp, then both of those will sound great with a TS in front. Just try it, if it sounds good, use it, if not, don't.
+1, throwing all the ODs and distortions in front of a new amp is one of the first things I do when I get it. Especially the TS7 and the RAT with very low distortion have sounded good on almost everything I've tried; SS and emulation amps included.
