Unless you plan to do something different, the FETs will also be supporting the weight of the entire ESC and all the G forces will be acting on the FETs.

This is true. The esc really needs to be mounted in some manner, then the heatsink can just be used to remove heat.
I do worry about the shock, not sure how that will affect stuff.
I do know that if you do not mount an esc sollidly you will have issues with it. That is whay I use double sided tape and zipties whenever possible.
