That’s very clever.
That said, the high voltages aren’t too big of a deal. If a neophyte like me can build a PSU for nixies, anybody can.
The hard thing these days is the ever dwindling parts supply. The big and pretty tubes are very rare and expensive now. IN12s are still plentiful but they definitely lack the panache of an IN14 or IN18.
