Do you pay any attention at all to the other posts here? I've said - more than once - that I've been modding this game (since the day I brought it home).
Yes, I can get anything in the game, mod pretty much anything in the game and am in the process of working out all the details. I've written custom scripts, created custom items and characters and a bunch of other things just to see what is and isn't possible this time around.
The biggest hitch I've hit so far is the scripting. There is considerably more to the scripts this time and the compiler I used with the first game doesn't like a lot of the new commands, so I'm limited as to what I can do with scripts... which is a shame considering all the stuff they've added. I'm assuming when the PC version comes out, someone will release a compatible compiler and then I'll be set.
I'm thinking about releasing a mod for this game that I've been using for testing. At the moment, it does the following:
Change alignment - Light/Dark 100%
Add/Remove party members (this can include custom NPC's)
Equip creature items - hides/claws etc.
Load custom inventory scripts
... and I'm adding a medstation and workbench to it so I have access to them at any time (remember, I said "testing"

).
I may also add a teleport function, give experience, change appearence, and a few other things I've been messing with.
So uh, yeah, it's being done. Telling you how is another matter since there's a shitload of new things to sort through (I don't plan on keeping it a secret though, so stick around) and I've only been at it for a few days.
