Active tube ribbon mic

Here's an idea for a tube ribbon mic:

Ribbon motor  - LL2916 1:110 transformer - EF86 pentode - 1/2E88CC triode gain - global negative feedback - 1/2 E88CC DC cathode follower - 200:200 output transformer - pad switch optional

It's sort of like a REDD .47 preamp built into the mic, it would need a big body to fit two tubes and two transformers (like the SE Gemini). The idea is that the 1:110 transformer can replace the usual 1:37 and 1:7.

Would this work? Or would it need an even higher turns ratio (37x7=259)?

I'm having trouble finding a suitable looking body to fit all that gubbins in, so I might substitute the EF86 for a 5840 subminiature pentode and the E88CC for a 6111 subminiature twin-triode, with values something like this

5840 pentode
Vsupply 150V
Ra 270K
Rg2 820K
Rk 1K5
Z following stage 1M
Vin 0.1Vrms
Vout/Vin 155
THD 2.4%

6111 subminiature twin triode
Vsupply 150V
Ra 10K
Vg -3V
Ia 4.5mA
Rk 680R
