NMF over CA-filled gaps

What paint are you planning to use? You can prime with anything to protect the plastic from the effects of the lacquer based paint or primer. If the paint requires a specific lacquer based primer, there is nothing stopping you from even giving it an acrylic pre primer first.

I manufacture two NMF paint lines...one enamel and one acrylic. NO LACQUERS used in these products!

What Gerald said. In a nutshell it don't matter, just primer it with something. Personally I use Tamiya fine spray primer. The primer won't do weird stuff and show your seams through the paint. Prime, sand and polish, then paint. All will be well with the world.

Not to worry. I have never had lacquer based paints affect CA.  And, like someone else said, you can put Alclad, at least, down on enamel. I use black enamel all the time under alclad.  Besides, I put the black paint down on real primer.

Alclad should be used over black not as a primer (for chemical compatibility) but for its reflective properties.  The alclad should go down very thin.  So as long as you have a good glossy black coat, it doesn't matter how you got it, whether over primer or over bare plastic.
