If you were building a Trainwreck clone instead of a Dumble clone, you could even name it "Janky."

I would say use the quad, or build a 50W with a Vibrosonic or Bassman OT, and use a Bassman PT. That's what HAD did for 50W, and that works bigtime!
...big fan of BF/SF Bassman trannies here.

Re: Fender Twin Iron; Dumble 50 watt
Here's how it works:
if you have a 2Kpri fender twin transformer(for example) and you put an 8ohm speaker onto the 4ohm transformer tap then you will create a 4kpri impedance as seen by the valves.
if you want transformer saturation then forget it, if you want bass responce then go for it.
as for tonality i have no idea, but it will work.
dont the trainwrecks use hifi transformers?
i think i remember reading that stevie ray vaughan used 100watt transformers in his 50watt vibroverbs, he would have done the impedance mismatch thing im sure as using 2 tubes in a 100 watt amp will make the tubes work really hard.
