You have to edit the item's UTI to change its animation behaviour.

(click to big)
On the left is the staff open in TLKedit, on the right is item_variations.gda open for a point of reference, NOT editing.
You can see the circled 3052 on the left (the uti), is mirrored on the right in item_variations, this is the model number. Changing this in the UTI changes the item's appearance. If you wanted to change the staff to look like Bethany's staff, you would change 3052 to 3051
in the item's uti file.
In this way you can have a staff, that uses nearly any model listed in item_variations.gda or similar...
Now to how it animates, look to the left again. Underlined is baseitem with a value of 1200. 1200 is mage staff. I'm sure these numbers are listed somewhere but I don't know and haven't bothered to have a real look. Through basic trial and error I have this list
1000 - one hand sword
1001 - two hand melee
1100 - dagger
1101 - bow
1102 -
bianca1200 - mage staff
Change that 1200 in the UTI to 1001 and the staff will now animate, including how it hangs on back, like a two handed weapon.
Under the properties list (green folder) are the item UTI's damage, restrictions etc. You don't really need to change these unless you're wanted to tweak damage or powers. I only mention it because there is also a baseitem entry in there, but this just relates to how the game treats the item (who can hold it, what tab it shows up in a shop etc).
Now the bad stuff:

Ouch that smarts, I guess its just for blood mages.

To get an item's UTI you need to extract it from your game's 2da.rim file, or you can extract it from a mod's erf of it like from Sunnie's item pack. You need tlkedit to edit it, and erfpack to repackaged it fit for your override folder.
If anyone has more time to figure out where the baseitems are listed, or they just happen to work out if there is one for
spears there's a guy waiting for that kind of mod. I just don't have the time/know how to do it.
