I think this is the best suggestion so far. The OP's amp picture doesn't display inline, so here it is in jpeg format:

I agree. There are compelling reasons it is good match. Also, it is wide enough to accommodate the head neatly. Only question for me is its ability to go low, round and warm. Seems like a small volume cab. Anyone? Can it go old-school thump?
The SL115 ticks a few boxes: Single neo 15 (no tweet), weighs 34lbs. Based on the 400w power rating and the availability of 4 and 8 ohm versions, I'd guess the driver is a version of the Faital 15PR400. And, the grill style of the Aguilar SL115 is already a decent style match to this head. With customization of the grill, it could be much closer.
