Trainz

I want to see if I can modify the AEM-7 created by Virtual Beach Grove. Specifically the cab, which is the generic European electric loco cab with the driver seat on the LHS. I know that there is a version of that cab but mirrored so that the driver seat is on the RHS. I wanted see if there was a way to swap out its default cab with the mirrored version of that cab. I've also heard there is another version of this AEM-7 with a more accurate cab but I'm having a trouble tracking it down so the cab swap will have to do. Anyways, is there a way to edit the cab without turning the AEM-7 faulty?

(sorry for my poor wording. Also, I think this might be asking too much but is there a way to edit the engine specs? VBG Aem-7's default power is pretty lackluster; struggling with trains longer than 5 to 6 cars)
