which I imagine will be a challenging combine?

Well, in PixInsight it’s not that bad, you can use ChannelCombination+NB_Script or just PixelMath. It’s just the matter of choosing the right balance that pleases eyes.

Another way to create a synthetic/super luminance is to use ImageIntegration without a rejection algorithm. The benefit of ImageIntegration is that it will weight the contribution of each "sub" by estimated SNR.

Is it not the same as adding up all channels in PixelMath with identical weights (1/3 in this case)?
1/3*L + 1/3*Ha + 1/3*O3
