RF Modding possibility & paying people to implement it:

Ive come up with an intresting mod concept, willing to pay people to implement it. My first step is deciding on what platform to develope it on. Right now its between crysis and this game. I have a bit of experience using blender and Ive been in a  few mod teams in the past, most notably the 7 Deadly Sins mod for sins of a solar empire, known as genocyber so I have  a bit of experience in the area of modding.

Both Games look amazing, but RF:G's geomod 2.0 and havok seem more dynamic then the cryengine 2 in terms of gameplay so If I cant Implement my mod on RF:G then I will use cryengine 2.

My main concerns:

Can you import custom models? Meshs, sounds, textures & animations?
Can you edit the maps?
Can you add a new multiplayer mode?
Can you add a custom in game UI?
Can you add custom menues?
Can you add custom weapon effects?
Can you add custom patricle & physics effects?
Cand you add/edit the ai and add custom scripts?
Can you add a ui to add/edit units/upgrades on vehicles and ai teammates?
Can you add a function to allow you to issue commands to your ai teammates?

The mod concept:

The concept is to turn RF:G into a 3erd person tactical stratagey game and add 2 new factions with a whole host of new weapons, vehicles and terrain pieces. This is intended to be a multiplayer mod, where there are 30 people on each team, each team has access to a huge range of weapons/vehicles that you can upgrade and purchase before the match starts similar to empire total war online matches and then battle for contol of victory locations similar to dawn of war 2 online matches.

As the match progress from tier 1 to tier 3 what I like to call 'conflict escalation' occures were higher level tech is unlocked which you can then purchase to get airdropped to your squads of ai controlled troops.

Conclusion:

I know much of this is possible to implement on cryengine 2, the question is, can you implement it in RF:G?
