If you look inside the game's data, making them playable would result in significantly lower quality. The Harrier and F-117 are both direct ports from ACAH/Infinity that have much lower resolution and detail. Those models have only 1k texture. Player texture is 4k while regular NPCs are usually 2k. Playable versions of those planes would have to be remade from ground up to scale with the other playable aircraft. Or if you can stand playing a low quality eyesore after seeing crisp 4k planes, there might be a way to model switch the planes like HAWX or something.
