Based on everything I have read over there, I doubt that OT/George would have any issues with the designers using their own designs to make other stuff. And since the original sculpts also belong to the designers, I doubt there would be any problem with them reproducing them and selling them. However, that doesn't make any financial sense, as they can buy the figures from the factory for less than $1 each, hence negating any need for a silicone/rubber repro.
But if they were to do t-shirts, posters, comic books, new sculpts of the character, etc., I honestly don't see George having any issue with it as he has already stated that OT does not own the character designs.
I'm not hugging any 
but I am a huge fan of the whole OMFG idea. Their group got together and designed a kick ass group of figures for Series 1 and were able to, because of Matt's contact with his Glyos factory, get the opportunity to have them mass produced for a very decent price. The did the fund-raising, offered independent dealers (such as myself, U of M, Rotofugi, etc.) an opportunity to buy in early, and gave the designers the ability to pick up some exclusive colored stock (cheap) for resale, too.
Funding transpired, and the line is a success.
OT owns OMFG, the artists own their characters.
OT wins because they have another successful line (like they do with Gwins and Zombies).
The artists win because they have their character (which they still retain all rights to) as part of a larger, successful line. They can now market the hell out of their character and even use that as a stepping stone to launch other characters that they have, as their audience/exposure is now exponentially bigger. I am going to take a guess and say that they can also order other colors of their figures in low runs, now, too. We also do not know if the artists get a small residual from the OT sales of OMFG. They might.
The OT community wins because they get to lay claim to having a hand in launching an incredible new line AND the figures are very fairly priced at $10 for a regular version and up to $15 for variant colors. Had they not been able to go PVC from Matt's factory, each figure would be $10-$20 a pop, instead of $2-$3 per.
In my opinion, that is a huge win all the way around.
To give it a different perspective, imagine if this were an entirely LRG created project. Imagine the same facts, different names.
So why hasn't LRG done something similar? There is loads of talent all over this board. Why not mass produce a 3 or 4 pack of tiny figures overseas like they have? I know most of the artists here collab together and get stuff produced and it's usually in a very nice squishy-firm rubber but the idea of an official LRG release is kind of awesome. I would imagine it would cover the cost of itself easily or even with a kickstarter. Then having possible profits help pay the hosting fees and whatnot for this place would probably be helpful. I do realize i haven't been here long and it's quite possible it has been discussed and or attempted in the past but i figure it couldn't hurt to ask.
