There are two independent issues:

1. Can it be done technically
2. is it legal to do so

I'm no expert on either, but I could for example, send someone a vue file with all objects and textures included, and they could open it fine, but if I sent them any poser content or  vue content, I'm pretty sure this is illegal.

Being that it is a public venture, it is quite possible the merchant that I bought the content from will find out about it. I do not want the legal sharks knocking at my door.
In fact you maybe liable too as an organizer, and it  would be a shame if a public spirited person like you gets in trouble.

So, I understand you are keen to try it out to see if the technical part would work, but I think you should FIRST officially contact VUE & cornucopia3d and also poser content sellers like daz3d, content paradise and of course the market place here.
If you dont have their consent, I for one wouldnt want to be involved, and I dont think others should either, not worth it in my opinion.
