Would there be any value in making my own silicon based power supply to feed this thing?

I do it all the time!
The hardest part is finding a suitable power transformer or two.
I've used power transformers from scrap test equipment, UHF converters etc.
You need one with a 120 and a 6.3 volt secondary. The filament circuit needs about 125 to 150ma, depending on the number of tubes. A bridge rectifier and large value, low voltage capacitors and a suitable voltage divider or a LM type voltage regulator chip.
The B+ is the easy part. A half wave simple B+ source providing 90-100 volts dc.
