Do you have some time frame in mind for your mod? The current working DwigMod version has a serious boost in the number of new units, but I expect I won't be able to release it until the end of this month or the beginning of next. If you had a smaller time frame in mind for your mod and are still in need of units, I'd be happy to toss over what units I have so far for you to sort through if it helps your mod out.
(New units so far include Dryad, Medusa, Stag Beetle, Elven Lord, Phantom Warrior, Nightingale, Nightmare, Ghoul, Valkyrie, Demon, Naiad, Golem, Astra, Gremlin, Glade Sprite, Kraken, Great Ape, Liche, Glutton Magi, Chill Falcon, Charlatan, Eyes of the Deep, Gnoll Halberdier, and various ships <Dragon Ship, Bombardier, Steambarge, Firemoth, Wavelance, more>. All of the racial priests are now recolored. Units are still being added at the rate of one or two every day or two.)
Just offering in case you still need to fill some unit gaps and were planning to release sooner than I am. Good luck!
