A Doug Ritter action figure would have to be at least as big as the first GI Joes instead of the more typical 3"-4" figures most kids are used to. Otherwise the PSK contents would be too tiny. That size would make the airplanes and wheeled vehicles too expensive for me, I mean "most kids", to get for the holidays.

Then I can just picture the "Doug Litter" knockoffs that would spring up at a cheaper price, but with faulty Kung Fu Grip and would not grip flight yoke properly.

That was just the first couple search results, I bet a picture of him could be found easily enough
