I certainly doubt that. But if you have an idea for a total conversion maybe you could talk to StarDock about it and they might green light it?

from wikipedia

In December 2003, TGTSoft sued Stardock and Brad Wardell for declarative relief, claiming that they should be able to use the IconPackager .iptheme file format without charge. Many open source programs do read and write proprietary file formats without paying royalties—for example, OpenOffice.org reads and writes Word, Excel, PowerPoint and other Microsoft Office  files. However, Stardock maintained that they should be entitled to royalties or a license fee on such software, particularly as TGTSoft was charging money for their products and because it was considered likely that their users would use the WinCustomize libraries, which are run with help (monetary and otherwise) from Stardock. The case was eventually settled out of court, with TGTSoft licensing the format for use with their products.

Modding is a way for fans to participate to the game's development, not a way to make a quick buck.  That's why modders are called fans and not employees.

Well if you make a great mod, and not just some races, a lot of dev teams these days look at modders for potential new workers and companies look at high profile mods for stand alone games.

fujisawasensei, yes I know and I appreciate that; it is so cool to see the mods a lot of people have already made without any hopes of financial reward.

When it comes to reskinning an already exsiting model or playing with the particle system it is realitively easy to make changes to the game. I was hoping to make brand new races, new skills, and more monsters then the common darkiling, spider, wolf, bear, bandit. I am a fan and will dabble in mods here and there, but I was hoping that there might have been a monetary way to drive full fledged mods.

Moddling, unwrapping, skinning, rigging, and animating a entirely new 3d asset is something beyond the skills of many, but more importantly, even as a fan it would take a very long time to produce a new 3d asset on a fan's schedule.

So though we will see some awesome mods, I think it is safe to say that the primary bottleneck for modders is going to be good 3d assets. Lets hope that I am completely wrong, which is likely

Edit: In the time it took me to respond to fujisawasensei several more people posted.

So as a general response, I think I would be interested to hear from stardock concerning this. The nice thing about selling a mod would be no one would buy a mod if it was pathetic, thus only truly original mods could be sold in the first place. So I will sit tight and wait to see their response, and if it is "no" then I will still be quite content with my new game Elemental.

also, if you make awesome enough mods, you can find yourself a job

my recommendation would be to talk to stardock/brad and maybe they would be cool with it on some level, they are unlike any other game company. 

And possibly the most creepiest level in a game ever!

Develop a working prototype (alpha/beta level to prove you can do what you say) and come up with a proposal, then talk to Stardock!

There a plenty of examples of game mods that became expansion packs or games.

- The Fall from Heaven 2 Mod, is now being developed into it's own game.

- The mod War Plan Orange for War in the Pacific, became it's own game .

- War in the Pacific Admirals Edition was done mostly by moders.

- Several games for the unreal engine started out as mods.
