Thanks Skuzzy, but....could you reconsider?
To put a number on my problem, which may also be a problem for other skinners - my P-38 resources are several Osprey books, David Donald's American Warplanes of WWII, and Gunston's Fighting Aircraft of WWII. With this selection of books, I have a total of about 100 P-38 profile examples. But only 8 of these are P-38Gs, and one of
those is the AH2 default skin.
Perhaps the G suffers from middle child syndrome, I don't know

But the vast majority of interesting skins for the small intake 38s seem to be in the F and H series.
Irv Ethell's "Tangerine" , Tom Lynch's shark-mouthed P-38H, Impossible Ince, 23 Ski Doo, Miss Fru Fru, Porky III - they'll all be precluded by this restriction.
Not sure how other skinners and guys with really big reference libraries feel about the paucity of good 'G' subjects.
EDIT: It's a can of worms, Capt Hilts. The shape of the 'G' may match the 'F' and 'H', but there are performance differences, as you noted. Not so with the 51B and 51C. I don't know if the performance differences are large enough to warrant modelling them - and that would be a shame because there are some cool skins for the F and H that we'd be missing out on.
Maybe we could do the F and H skins and then if they are ever modelled, the skins could be moved over to the proper model?
