Hey Ultra M,
How goes? I think it's a great Idea, extremely huge project. personally, I don't keep boxes much, mainly out of need to conserve space. I know there are definitely collectors out there who do keep boxes though, I'm not sure in the numbers you are thinking of.

The idea of designing and developing Transformers is something I've been tooling around in my head for a long time. If done well, there would be a fairly big market I think. At this stage i would consider myself extremely novice at toy design, but if you're looking for something in the future, and I have the time I'd be interested in lending a hand.

Definitely an admirable undertaking though.
All the best.
UltraM
