I have successfully gotten 3 plugins to work in goty and im sure all the other ones will work as well... heres the instructions:
Note: Ok, after further inspection, i seriously think you can skip steps 3-6...but if your having probs, do them all.
1. Download and unzip the mod
2. Put the esp file in both the GOTY/Data Files/ directory AND the cache Data Files directory
Note: this is NOT the cache in TDATA or UDATA, mine was in X:/Data Files
3. Copy an original
morrowind default.xbe to the GOTY default.xbe
4. Edit the
morrowind.ini file and add lines for each mod, like this:
[Game Files]
GameFile0=
Morrowind.esm
GameFile1=aire.esp
GameFile2=animal.esp
GameFile3=Mesa.esp
5. Load your copied default.xbe and load a saved game(NOTE in this screen only orig mw saves are available, but have no fear

)
6. It will load a few times and go back to title screen...from there click load and the game you wanna play(GOTY Saves included

)
Thats it! You now are playing teh mods in the GOTY edition of MW!
Special thanks to Orochi and hammy for ideas and support!
EDIT: Plugins with meshes, textures,etc ARE playable, just create the folders
within BOTH the Data Files directories
Eg:
E:/games/MW_GOTY/Data Files/textures/
X:/Data Files/textures/
Have fun!!!
Peace!
