That's what I do, but mainly I was trying to think of ways the OP can achieve that he wants to do. Do you use C1 now for your work or just visiting this thread?
I use C1 mostly (I really like the V7 quality improvements), and RawTherapee to see if there is something that can be improved by approaching the file from a different angle.
Some things, e.g. darkframe subtraction, can only be done with RawTherapee, which also gives a lot of control over the Raw conversion process, i.e. pre-processing including the possibility to adjust the black and white points per channel (can e.g. help with clipped channel correction).
