Unlikely (Jack Archer might not be Macross canon, but is RT canon).
I'm wondering about "double-dipping" personally, because if some of the early Shadow Force images still apply, then all Toynami have to do is take their upcoming Shadow Fighter, make new wings with missile pods imbedded, and bingo bango another 80 bucks for an official Shadow Force design...
But on the other hand that may get a MPC Beta made, as they just need to switch out the sensor boom for a synchro cannon of a New Gen Beta to make it a Shadow Force version, meaning that Toynami would get more use out of any Beta molds.
