Per request, I'm going to go into more detail between the two types of seats anf their cover compatibility. Here'* a side-by-side comparo of the two:
The one on the left is from the SSEi (9 switch controler) and on the right is the one from the SE (6 way power, manual recline)
Now for a rear view. First up is the SSEi:
The SSEi with the rear flap up:
Then the SE:
You can see how the construction of the two covers are very different and why I decided to not go any further with the swap. Now that I look at them side by side, I don't even think they would fit at all.
