64 bit, and possible workarounds?

I love Notion 3. Or, to be more precise, I love the idea of it. Unfortunately, in its current 32 bit form, I am finding it almost useless for me. I absolutely love the interface, the concept, everything except that the lack of a 64 bit version is keeping me from utilizing my orchestral VSTis to their fullest.
With the developers being suspiciously quiet about updates, I am wondering if anyone has some workarounds for accesing 64 bit plugins? I've tried using the MIDI out ports, but unfortunately I have not been able to find virtual MIDI drivers that work in Notion as well as in Cubase 5 64 bit. A shame, because this would really be the ideal way of working for me, using Notion for sequencing and Cubase for mixing/VSTi hosting and final tweaking of the MIDI data.
Another possible workaround is to use Vienna Ensemble Pro, but I really would rather avoid spending money on something I only need as a workaround.
Has anyone come up with a good method for accessing 64 bit VSTis? Or ideally, for routing MIDI between Notion 3 and Cubase 5 64 bit?
