Currently it uses DAE to go to CE. When they have full fbx supports this could be possible. The send to command in the Autodesk apps i figure uses fbx for translation. I know it well given my Maya to Motionbuilder work. You wont get Autodesk writing it first though since the plugin is mll and Autodesk cant hack that open. Wish i could help and like you i would have to wait. In that position i would stick to Unreal. Like how for certain work i use Unreal and my dev i use CE. I wrote why earlier. Same case but in yours it would be different reasons.
