As an ambient composer, myself I understand your pain but that is the unavoidable fate of all abandoware technologies. Abandonware technologies however can be used through the use of emulators. If I can use my first computer that my father bought in 1988 (Amstrad CPC 6128) with its magnificent 4mhz CPU and mindblowing 128kb memory from any OS (including iOS and Android) via emulators. I am sure using 32 bit VSTs and AUs should be a walk in the park with Virtualbox. All you will have to do is bounce those plugins to audio and move the audio to your 64bit OS or even (probably its possible) make the two OS talk to each other so you can use both 32 and 64 bit versions at the same time.
