Nice to see it! I had a pretty big hand in making these suckers, worked at New World Computing during that era...
I'm thinking I'd better not elaborate on the particulars or give out any personally identifying information, but maybe I'll pop into their discord and make myself vaguely available (if I could even be of any help).
Oh wow! I found out about the project recently and had no idea sharing it could grab the attention of an NWC dev! I've played the series to death so I'm sure I've killed you a couple of times in the secret NWC office levels.
If it doesn't impose any ethical / legal questions (a la an ex-Windows dev working on ReactOS) I'm sure your expertise could be extremely valuable.
I'm not sure if by that era you mean that you strictly worked on 6-8, but you may also be interested that ScummVM recently started supporting the Xeen titles and even more recently started working on implementing MM1 & 2[0]!
ScummVM aims for authenticity, so at least in its initial implementation the UI would most likely be exactly the same as it was at release, but it does open the door for modification I suppose - you may not see those enhancements made directly in the ScummVM tree though.
I've definitely seen engines with optional UI/QOL improvements included in ScummVM. Ultima VI, for instance, has a number of options that make it play a little closer to Ultima VII.
What a trip down memory lane... I only had access to the Xeen titles in my younger years, but they absolutely had a big influence on me, and I still remember them fondly.
In a way, I would almost hate to see it again- nostalgia almost certainly is kinder than reality.
