I would be! I might not be able to help you with the actual coding, but I can throw around some ideas if you want to... You might want to check the nwesGroups of rec.games.roguelike.developement and r.g.r.misc, DomII has been mentioned at least once in the latter.

Could you tell us what you have planned? Especially these three questions are rather important for me. I have dreamed about Dominions-based roleplaying game a few times myself, so I have some of my own ideas to post too.

What language are you going to write the game in? If you want help others have to know if they can help...

What kind of system are you going to use?

My answer: Dominions RPG system. With DomRPG I mean system with Att, Def, Str, Prot, etc. that are compared with open-ended 2d6 roll, like in the game.

What kind of magic system are you considering?

My answer: Schools and Paths. One way to cover the Schools and Paths is to give the character knowledge in the first and power in the second and use DomII spells. This would highly unbalance the system towards Evocation and away from Conjuration and Blood as all kind of summons would be very expensive, so we would have to make a workaround.
One possibility is to use Rules of Magic from Ars Magica, pen&paper rpg that IW team plays/played. In it, no magic or magical effect is permanent without use of Vis, magical power found in _gems_ and few other forms... With this even beginning Conjurors without gems/vis would be able to create a Vineman, but it would dissipate after a while.
4th edition of Ars Magica can be legally downloaded from somewhere, I don't remember the exact place but can look it out if you are interested.
