FWIW I have yet to find success at this.
For me personally, I'd rather use the Reaper native plugins for most of the FX that are available as PGMusic DX FX (or many times use other options I have available), but one guy I am working with likes the PG FX, so I did make a modest effort to find them in Reaper .. no joy so far.
Granted I am running 64 bit Reaper on the machines that have Reaper, so can't confirm whether using 32 bit Reaper would make a difference. I suppose it's possible.

I wouldn't discard VintageGibson's response without trying it (if you want it bad enough).
I can see how it's possible for 32 bit DX FX to work in a 32 bit host compared to 64.
Just know there may be trade offs in the other direction; other 64 bit plugins will likely not be available natively in a 32 bit host.
So you *may* gain PGMusic FX and lose many others.
