That would probably be an interesting amp, but it wouldn't be a Model T.
Ditto. You could replace the phrase "a ptp model t 1st gen" in your post with "an amp" and probably been more accurate.
You could theoretically
clone a Model T, but changing output; transformers, tube complements, etc. and adding gain stages would make it an entirely
different animal.
Many people think that it's just a matter of copying a circuit from a schematic and scaling the values up/down, but that doesn't work.
What makes a Model T a Model T, or
any amp what it is, is the "big picture"; the sum total of
all of the parts working together. The various stages "talk" to each else on several levels, and different components will behave differently when used together to affect the overall result.
This is one of the reasons that with so many gazillion different amps available there are just a
handful of iconic, “got it right” designs; 200S, B15, Marshall Bluesbreaker, etc., of course everyone has their personal favorites, but my point is that it's not "plug 'n play". It’s not like a component home theater or PA rig, where you can pretty much just plug any preamp into any power amp and use whatever.
An integrated, hand wired tube MI amp takes on its characteristics based on the big picture, the sum total of its parts working together. You can’t just, for example, copy the schematic of a Model T preamp and “plug it into” the schematic for the output stage of a Vox AC30 to get a 30 watt Model T, or use a Model T schematic and just use smaller transformers and a pair of 6V6’s to get a “20-30 watt Model T”.
You
might end up with a killer amp, but as Isaac says; “it wouldn't be a Model T”, and IMO even using “Model T” in the description is a little inaccurate as to the project you are describing.
Good luck, and be sure to post about how it works out!
By the way, I'm moving this to DIY.
