Planning next amp build- 40-50W Fender brownface mishmash

[MikeW86]

This is what I'd like..

-2x6L6/5881
-solid state rectifier
-harmonic tremolo
-6G6-B bassman output transformer
-2x12 combo

Fender never made an amp exactly like this, there are very few brown-era amp kits available, and the few that are available don't have harmonic tremolo. I'll most likely have to have a chassis and cabinet custom made, and I don't know the best way to figure out what power transformer I'll need. Any thoughts as to the feasibility of a build like this?

I'll trade you a Vibrasonic 6G13-A for your Bandmaster
