Given that the currents are pretty modest, the absolute voltage isn't critical and it's a DC rail (ie no high frequency signals) , I don't think it's a big deal unless you're going to push the separation concept to crazy levels. I have a design where there's 45cm of 7/0.2 wire between the HV PSU and the nixie board, and there's no issue. Just put a small cap on the board to provide some local energy storage to stabilise the HV rail. 1uF 250V electrolytic works fine in my application.
