To the best of my knowledge, the seat bolt mounting holes are consistent thru all years and models. Seats from a Cayenne will bolt into a Touareg and vice versa.
The problem is the electronics. If you want it to be plug and play, you need to stay inside certain areas.
In your case, I would suspect that any non-memory seat should interchange with any non-memory seat. Any memory seat should interchange with any memory seat. Later years had ventilated seats and that would be a third setup, not electrically compatible with the other two.
The problem will be if you try to go from non-memory to memory or vice versa. The memory seat requires different wiring and there is a control module added to that system.
The non-memory seat obviously lacks the additional wiring and control module.
Swaps between different seats can be done, but you are going to be doing a lot of re-wiring.
