Animal Companions for Rangers and Druids in IWD:EE?

I was so sad to see that Rangers and Druids have no animal companions in IWD:EE. I know it's true to the original but still...with IWD II:EE probably never happening, this is the only game set in IWD proper and it would be wonderful to just have the same options as in BG II:EE.

This awesome mod: https://forums.beamdog.com/discussion/50975/mod-animal-companions-for-rangers-and-druids-for-bg1ee-sod-bg2ee-eet/p1 lets rangers and druids have nameable and leveling animal companions for BG and BG EEs, anyone want to take a stab at making it work in IWD:EE? I'd be so grateful!
