Can I synthesize luminance flats from RGB flats?

When I set up my club's remote scope, I forgot to schedule luminance flats. I do have a full set of RGB flats from the night but they are insufficient to eliminate what I assume are some condensation artefacts. Since the artefacts are very similar on the RGB filters, I assume they are on either the scope or the sensor.

If I integrate without the luminance frames, correction is very good. However, if I include the luminance frames, the resulting image shows the artefacts.

Is there a way I can use the RGB flats to calibrate the luminance frames or, synthesize a Luminance flat from the RGB flats?

Bump ... anyone have any thoughts?

In his video tutorial on this page David Colonnello shows how to make a synthetic luminance from RGB files.
