Had I been a developer as 3dgs, then I would have biten the bite and bought the License, and tried my best efforts on seeing if the company was able to port the whole 3dgs or best parts of it for the console. If the development was really succesful, then would have thought about getting company's approval.

As a programmer and developer I know that, it is only to change from dx to propriety underlying graphics engine. And as standard the programming would be in 'C' or a variant of it. The whole thing in a dev suit like yours is collision detection and animation engine and such which are at higher level of classes. And as you are already able to give users the benefit of a scripting engine, there would be no need for users to know the inner workings of the console.

As an example take the case of TSE (Torque) which has been ported to xbox360, where the console developer has itself helped the TSE in porting it for their console.

But as a side note I would like to express my wishes that the company should focus on seeing if they are really able to do proting. If succesful then have a decent license of it for the would be developers.

Even Nintendo can be persuaded to be a partener in licensing of the engine, opening the market widely.

Indie developers are for fun and maybe some money and surely they can't give the big houses any tough competition.
