Hello,
We have had similar discussions about this sort of solution in
this thread.
You could either build a 32bit DAW to host VC in, then control it over LAN/MIDI, or you could just have the one 64bit DAW and host a virtual machine inside that computer - the virtual box being 32bit. Either method would work, I think. The former would give you more power, but would be more expensive and take up more physical space. The latter is cheaper but potentially liable to bugs as its a fairly experimental setup...
