Egm Mass Effect 3

As way of background I am the author of Expanded Galaxy Mod, a SP mod that allows customisation of the Normandy, new weapons, armors and lots of RPG style improvements.
Egm Mass Effect 3A couple of players are very keen for me to create a patch to allow then to use a controller and I wanted some advice on how to do this.

Aug 04, 2020 The Expanded Galaxy Mod adds a huge number of changes, both large and small, to improve the overall gameplay of Mass Effect 3, giving the user a more personalized experience. Mass Effect 3: EGM Question/bug? Hello, So I decided to give ME3 another go but with the rather well known Expanded Galaxy mod (and nothing else).

There are going to be quite a few conflicts: EGM mods a lot of the Normandy so there are many GUI aspects like galaxy map, war asset terminal, mail terminal. EGM also has slightly customised GUI elements.
I see you have created an GUI injector which could be incredibly useful in swapping in compatible parts.
So what would be the best way to go about creating a patch?
Do I need to do anything else other than edit GUI elements?
The SP controller mod - it overwrites all changes to tlks? Or just the particular buttons it uses?
