Well, I was thinking of HylaFAX running on another box, with some type 
of IAX2 "virtual FAX modem" client running on the same machine, using 
IAX2 to communicate to Asterisk. That would remove the CPU usage from 
the Asterisk box and put it where it belongs.

I'm curious how you think "HylaFAX would really slow things down", if 
you mean something other that CPU usage? I'd see adding HylaFAX to the 
mix as adding well-tested and reliable ECM, MR, MMR and other protocol 
support on top of the virtual modem you've already implemented, as well 
as supporting alternative FAX origination methods (email, print, etc.).
