Yes you can debayer RAW DSLR files to separate RGB channels. MAXIM does it. I think PixInsight will also read the files. Or try FITS liberator, free download from the NASA website maybe.

Will chew through your workflow though. On the colour combine I assume the ratio 1:1.22:1.77 is R as 1, G as 1.22 and B as 1.77?

All worth your learning. Yes RGB in that order. For a DSLR being more sensitive in the blues and greens I suspect you'll need to push the reds.
