Try 15's, honestly.

On occasion, mostly nights where my bass player is absent, I'll just throw my 2x15 in line with my T. The Cab the T powers is 4 ohms, so is the 2x15, put it at 2, and let it go. The bottom end fills out, you don't hear much high end clarity, that's what the 12s are for, but it really, really fills out the low-mids, and lows. It's a real thickener.

My Model T 1st Gen > 215s//412s = heaviest and best tone I could find. 15's is the key for bottom end...!

Hiwatt cabs with Fanes, Emperor cabs with v30's, maybe even some Orange cabs with v30s.

a pair of sunn 412s for guitar.
a 6x10 or 8x10 (8 10s gives you more standard impedances) with a 2x15 running JBL D140Fs.
For bass you might want a 1x18 front loaded cab without the folded horn.

my personal preferance would be 4x12s with 2x15s for guitar  and 1x18 with 6 or 8x10s for bass.
