Correct, there are a number of boards where this is the case.

Not it you also swap the compute lines. Given that VBat doesn't need
one, it's down to simply replacing "compute in7" by "compute in8".

Sounds good. Will be slightly different after you switch in7 and in8,
but all in all it should stay within a reasonable range.
