That's not what I would worry about.  A DC blocking cap will take care of 
that.  The purpose of the Hi-Z plat bias choke is to keep the RF off of 
the power supply components.  That's more of a problem.  So please 
explain how your idea prevents this from happening.

If you are talking about the choke for the filament supply, then you are 
correct, you can float everything at RF and so forth (AG6K recommends 
this for some tubes).  You can build smaller RF chokes for use at your 
high voltage/low current AC filament supply.
