Mike,
your still in grand rapids right?
Wolverine has a mold/model shop that would have adhesives for footwear, as well as perhaps some other things you may need. i dont know who all you have been talking too in the past year or so, but if im your best contact within WWW you should come to the Grid office downtown GR with what you have, we can talk a bit and maybe get you in touch with someone in the shop that you might be able to work with as far as tools, adhesives, etc.
