SolahmaJoe's Hangar of the Dispossessed mod for Battletech now includes the Phoenix Hawk!
Once you install the mod, you can and will fight and salvage the Phoenix Hawk, Warhammer, Marauder, and Marauder II during the procedurally generated missions!
I altered my game constants and started a new campaign with the Pixie as my starting ride, it is a thing of beauty!
Best,
mad
