Product suggestion - Separate 'Analogue Supply' PSU for NDS/555 combination

So, if the NDS does benefit from using 2 555 power supplies, in its very highest configuration, with one 555PS for the Digital, DAC + Clock and a separate 555PS for the Analogue Supply via the separate Burndy connections, with the separation right back to the mains connection - so a suggestion is for a separate 'upgrade' Power Supply just for a NDS using one 555 unit.

So this stand-alone supply would just be for Input 2 of the NDS, and is just the voltage rails needed for the analogue stage of the NDS, as per the diagram from the Whitepaper:

This saves the purchase of a complete 555 unit just for this area, with the 2nd Digital supply, DAC + Clock supply elements unused.

Either this could be HiCap size unit given its focus on the Analogue supply or a full-size unit - plus if there was any spare room in the case, given the reduced number of voltage regulation, is there any further improvement made to the supply rails, noise and regulation for these sensitive electronics - double DR circuity - a 'NDS DDR' PS?

How about it?

Thanks, Simon.
