2. If your luggage gets lost on the way to BRS, the airline is not required to transfer it to KL.
3. CO does not have to book the luggage through, and may not.
As long as the two airlines have an interline baggage agreement, there would be no problem even if they are not a part of the same alliance. I have done this many many times. If you are transferring to the other airline wihin 24 hours even different baggae rules are not a problem. It's possible one may run into an agent who would try to squueze some cash from one. But if one is fir, confident and polite, that can be overcome too.
