I don't see why not. The Imperial Star Destroyer has a still exclusive Imperial Officer, the Millennium Falcon has a Han Solo variant only available in one other set (the latest Mos Eisley Cantina), Clone Turbo Tank's soldier has a special helmet found here and the last Star Wars Advent Calendar, the TIE Interceptor's pilot also exclusive here and the 2014 Star Wars Advent Calendar, the X-Wing's pilot was an exclusive variant with new printing (torso & helmet), the AT-AT's driver limited to the Microfighter set and its larger latest version, same thing goes for the Republic Gunship's clone pilot, and to round up the ARC-170 Starfighter's clone pilot was an exclusive variant too. If LEGO is planning to design Microfighter sets around the Rebels universe, they could easily toss in any one of the main characters in there like Hera piloting her Ghost ship or The Inquisitor flying his TIE Advanced Prototype only in Microfighter form of course.
