So I can tell you my process and see if it make sense.
(this is in pixinsight)
After BG removal & stretch I combine SiiGOiii to make RBG.
I remove any greencast with SCNR
I then use a Ha in LRGB combination with Ha as L.
(I'm adapting my another workflow and have just realized I could have done LRGB directly but nevermind)

I don't use Pixinsight and I'm not a fan of NB. I prefer the beauty of a natural palette. However, I do appreciate an SHO image
if it's done correctly and the colours are rich and well balanced to reveal underlying processes.

Just a note, NB colours don't need to be psychedelic.

In reality I only have access to my Bortle 4 skies in my backyard so initially I jumped on the narrowband bandwagon.

Do you have a luminance filter? My advice would be to try either LRGB, RGB or straight SHO first. If you want an enhanced natural palette image, do LHa(RHa)G(BHa) (cf:
my version from 2009 - Bortle 4 skies at the time)
PS: If you know there's some Oiii signal present, you can also augment the blue and green channels with some Oiii data to taste; usually 20% and 10% respectively. I call that augmented natural palette.
