I don't know what your plans are for AH and TOD (where a J model might make perfect sense for the timeframe) but the J triggers my hangar queen alert.

It's nearly identical to the L minus a few horses here and there, dive flaps and a bit of gas.
F and G/H would be completely new and different toys and as far as I can see are better suited for scenario use.
F and H please

But then, every new plane is Good News.
Being a regular P-38 driver I'd rather sit out a few versions in favor of a new Japanese plane though
