Unfortunately it's not really possible to mix 32-bit and 64-bit code together within one single executable process... It is possible to do things like have separate .exe processes running, each of which are 32-bit and 64-bit and send data back and forth between them, but it would also be a lot of work to set things up in that way.

It's likely to be better to just try and convert everything over to 64-bit.
