I may trial some fins along the hatch edges just to see what happens.

I'd be interested in your results.
Surely someone else has tried it and reported their results, but apart from my data, I've never seen anyone else reduce drag by added long fins down each side of a rear hatch that has attached flow (and I assume, therefore, trailing vortices).
