Exo unit unlocks

What do people think of having the AI unlock units for use in Exos similarly to how they unlock regular ship types and guardians?  EG, the AI might unlock Laser, MLRS, and Infiltration Dire Guardians, plus Armored and Cursed Golems, and not use any other DGs or Golems in exos until the AIP goes up. 

I think this would be an improvement for the same reason it was an improvement for regular Guardians: more variation from game to game. 

It should always have H/Ks available, and I'm not sure there's enough variety in combat Spirecraft for it to make sense there.

Another complementary mechanic would be to have each exo strikeforce pick a favorite unit, similar to how planets have favorite units.  That would create more variation from exo to exo within a game.
