Importing Custom Items from BG:EE. Is it Possible?

To cut a long story short, I'm wanting to transfer some files from BG:EE that I made (custom items specifically), and plop them into BG2 without having to fully remake them.

I know that I'll have to remake their Dialog.tlk entries, that's not a problem. What I'm more concerned about is having to remake the items in question from scratch, and meticulously test and re-test everything again to make sure the functionality is the same as before.

Is this a possible shortcut? Is there a trick I don't know about that makes this easy?

(For Reference purposes, I've made all my modifications and items in Near Infinity)
