I tried 4Mal's MB 500 Fusion through my TC112v1 a while back, but only at home and only pretty briefly. It seemed just a little bit smoother than the MB500 to me, which is what 4Mal has also mentioned. I didn't mess with the distortion much, but it seemed pretty capable of going there.
Any chance you can make the Seattle GTG in May? Should be all those flavors and more in attendance, although I'm not sure which AK cabs will be there. TC112v3 and TC118 are already confirmed though.
Meanwhile, back at the ranch I'm building yet another DIY amp, this one formatted to fit nicely on top of my TC112 without overhang or having to stack pieces:
Hoping to have this one wrapped up in time for the GTG, which should be pretty doable.
