I wouldn't bother with monsters personally... Just curious for like the female shaman, you'd be using the fixed female shaman one, not MJ1990's rescript, right?
I personally think this is an excellent idea and have tried to do it a few times with my own ROM, usually fucked it up somewhere though lol.
A set of instructions based on these things wouldn't be a bad idea either, e.g. the weapon icon thing you're having troubles with should be mentioned somewhere, etc. So the limits of the ROMs and stuff are handily available.
That way they'd know how far they can go with stuff and that. /so non-specific
Edit: I also would SERIOUSLY recommend putting in the custom spell animations for Shaver and all that kind of stuff - inserting these is something that even I hate doing and I know what I'm doing - so I think it would be cool for this kind of stuff to be immediately available to noobs. It would allow them to have a higher quality of hack right off the bat
