I see two other conflicts, there's two laser sprite changing mods and two firestorm sprite changing mods. The Lasers can be fiddled with so you have your favorites from both without much conflict, but you should choose which firestorm mod you like better because otherwise the "Restyle" one will just overrule the "GFX" one.
You could also fiddle with those rulesets and assign one sprite to another craft, like I was thinking of making the "Restyle" version another kind of interceptor and the X-Com:EU version would be my firestorm. It's up to you if you want to go through the work for that though.
