Any help you can provide in these points would be (in my case at least) greatly appreciated!

Probably could be a clamp on mod but I would not recommend it. If you were local to me I would do all the work needed for duals all the way back in exchange for the 2 removed used cats.
Someone has posted what the car sounds like with the rear cats removed but kept the factory muffler. Sounded pretty good if I remember correctly. Just have to find it in an old thread...
