What won't work without the FRM? It looks like maybe the door latches are identified through the FRM which would prevent beinge able to select "Drive?" Anything else?
I think essentially not much will work without the CAS. There are several wakeuplines that are sequenced. Maybe you can get around it but I'm not sure. These modules weigh almost nothing and are by far the easiest, most reliable way to make the car work.

I have a feeling, again, the car will not be happy about the FRM being gone. It is responsible for all lighting functions, as well as general car operation. It's one of two places the VO and VIN gets stored (second is the CAS) so if you remove these I think you're going to have a problem.

Unless you're ripping everything out and running the DME completely alone the amount of work you're going to need to do to properly remove all this (if you can at all) is not worth the 4-5 lbs.

Removing the ABG module, airbags, and their associated wiring is literally half the weight of the whole car's electronics and can be done without any issues to the car other than turning off the check in the KOMBI. Second most beneficial is the audio harness, and then the whole roof harness. After that you have very little harness left and everything will still work as it should. After that your time and money can be much better spent elsewhere.
