Bringing in Ha after Star Color Calibration

I'm working on a galaxy image in LHaRGB and want to take advantage of Star Color Calibration.

My understanding is this can not be done with narrowband data in the mix.

Could I do an RGB Combine using LRGB, do Light Pollution and Background Calibration, and then go back to the RGB Tool and bring in Ha data, assigning it to Red?

You could, but I'm not sure that will get you the proper colors. When you have enough RGB, you can still try the star color calibration, I notice it does tend to give you pretty good calibration then still. It's not going to be perfect, for that you really need a regular RGB spectrum, but it can give you a good starting point and maybe even pleasing result.
