Thanks Unai. This has been suggested in the past by a few individuals and some other ways too. I'll try and summarize it for you.
OVERALL
It would be great to be able to pay the team a salary that matches their own now to get them to work on the game for a few months. Ultimately that IS the only way to get the game done in a short amount of time - that, and rent a place for the team to stay and make it... The question is how would you go about making that happen - legally - when you are working on intellectual property you don't own but a gigantic untouchable Hollywood studio does.
KICKSTARTER STYLE FUNDING
There is no denying this kind of thing could help with a project like ours. But it's highly unlikely we could ever attach a Kickstarter style setup to FoY itself. I'd need to speak to someone properly about it but I get the feeling even if the game is not for profit the fact a development budget has been formed by the general public could still present legal issues. That said, someone assured my Kickstarter IS just a form of donations.
LEC FUNDING
The idea has been put forward several times that we just get in touch with LucasArts, ask them to fund the project and then give it to them to sell. Or some variation of that. Again, in terms of getting the game made that could be very good - in terms of creative control, that could be a total disaster.
PRIVATE FUNDING
Some individuals have hinted at covering a monthly wage for the team, but I think that was just passing comments. Who'd be serious/crazy enough to do that, really?

Still, private investment is one of the best ways to cover the production costs, but we need a seriously dippy millionaire to consider it...
THE SOLUTIONS:
1) STAY FREE OF EVERYTHING. No-one is paid to make the game, no-one ever has to play the game, but the game gets made slower, over free, unpaid time from the developers. This is how we run it at the moment. There are limited legal issues (really just the use of the name and likeness Indiana Jones).
2) GO AHEAD AND RISK PROSECUTION. Run some kind of funding campaign directly related to FoY, risk being shut down. OR, risk the contact of LEC and ask if they want to fund and sell the game - but again risk a C&D.
3) DO THINGS IN THE BACKGROUND. This is my newest solution, and could herald some new answers. I'm doing what I can to get my business, game studio called Screen 7, up and running properly. If people support the company and the products then I'll be able to set aside a budget for getting something like FoY done. I could effectively, through the company, run an in-direct campaign, ie "Kickstart A Game Project" and then that would go into FoY, if that makes sense? So for now I'm hoping people will support the business, and if any Kickstart option looks possible - I think it would have to be more like a "development grant" through a studio rather than a direct cash-injection to the FoY project.
As always though, certainly listening out for ideas. And I know pay to get it made is one of the better solutions. It really needs some legal scrutiny, and some real establishment with the owners of the franchise, for it to ever be legit. It's never felt like we've been dancing on a legal knife-edge but it certainly would if we started a Kickstarter directly for FoY. Hope that answers some of your questions Unai, and feel free to keep the ideas coming

I will again dive into the legal mumbo jumbo of Kickstarter style things and see if funding a free game project will strike up massive legal arguments or not.
That said, if anyone does have a spare $200,000 - get in touch, and you can have the game in a few weeks time
