Oh good grief, I feel another RPG coming on

My Cloudship Atlantis game is coming to an end and I am currently putting together an Icar one. I need to fill the gap with something easy and the more I think about it, the more I want to write it.
Commando RPG
has started one but it's not near finished (I've asked for whatever he has for a look). I'd use a modified version of the Cloudship Atlantis rules where the players share a pool of dice in the middle of the table. Trying to do something you're not skilled for uses up these dice, having good ideas or putting effort in makes more of them. I will want to make the combat system a little more involved/interesting because it needs to be edgier than the swashbuckle of Cloudship Atlantis.
The setting would be 1939-1942 in a cinematic Europe where the team would be carrying out missions against the Nazis. A bit of Where Eagles Dare, Bridge Too Far, etc. Add to this a little bit of occult, Nazi mythos and how WW2 computer games treat their heroes and you have a wealth of missions that involve sneaking, speaking in German/French/Dutch/Italian accents, femme fatals, parachuting in, rushing toward Swiss border and stiff upper lips. It's more Special Operations Executive (precursor to SAS) than Royal Marine Commando but I intend to stick only loosely to the truth - my players aren't experts in WW2.
Anyone done this before? Anything I should avoid or do?
