I don't think any mods will work with Proportions except shipset graphics (remove AI files first if you want them to work as AI empires). Proportions changes just about everything, in ways that other mods don't. If you try Proportions and don't like some aspect that there is a specific partial mod for, you could try dumping that mod on top of it and see what happens, but I think usually you'd just get something weird.
