If you cap the extra resources you can get to 100MP, 40MU, 20FU it's not going to create spam.
The point of this is if let's say you have 95MP left, and 15 FU, you can trade that fuel for 100 MP and get an extra rifle squad. or if you have a spare 100MP and you want one more medkit but only have 10MU you can trade the MP for another 10MU. I don't think anyone likes buying a eng squad with a mine detector because thats all you can afford you'd be much happier with one more rifle squad with a nade.
I suggested this some time ago, but I forget what the mods said.
This could be done with resource for resource, with with PPs, or I think the best bet would be to pay with SPs.
25MP for 1 SP, 10MU for 1 SP, and 5 FU for 1 SP, something along those lines. And lets say these extra resources last you 3 games or something.
