I'm having trouble wrapping my head around this one. I've done a lot of Matchmoving and have a pretty good handle on camera set ups in various software, but what I can't for the life of me wrap my head around is how to add an additional move to a tracked vfx shot. A Camera Move extension I guess? Not sure what its called. Here's the situation:

I have a basic dolly move of our talent shot on green sitting on these CG "chairs"/pods. Piece of cake. It's super clean and pleanty of tracking markers. However, the director wants to add a virtual move off the top of the shot where the camera flies in from the other side of the room and then slows down and merges into our real camera move. I've tried a bunch of things but I'm not really sure what the best way to go about this is.

I'm compositing in After Effects and the CG is being done in C4D. I've sorta-kinda got something to work in after effects with a combination of 3D layers of the footage for the virtual move that cuts to a 2D layer for the real move that I've tried to line up perfectly.. but its just really not working to well. And then on top of that, how does that translate to the C4D render? Do I go through C4D first and try and get a good camera move down? Or do I start in AE? So confused?! I've never had to do this before.

here's a reference that I can think of off the top of my head. It's from the Matrix..... at :10 seconds in, the aerial shot that revolves around the truck flies into/merges into the live action plate:

I know it's not the best example but It's all I got! If anyone has ever done this type of shot before I'd appreciate your help! What ever your workflow was out of your matchmove software and what you would do in your compositing app.

Thanks a bunch folks!
