Firstly as Rewind and Eject

If you removed the false cockpit piece from the chest area and gave them the appropriate paintwork they would make passable Autobot casssetes their heads are even the same shape

The second idea is a bit more complicated but i was fiddling with my Alt Ravage and found once you've transformed him you can swing the back of the Corvette back together over his chest area in a look that to me is reminiscent of the original version of Overdrive.

I just need to work out where to scrounge some suitable arms from so you can turn his elbows to shoulders

You might check out a corvette bash I did into Punch/Counterpunch. 2 separate transformations into 2 different robots. In the kitbash gallery.
It may give you some ideas.
