I have a 2006 222…love it.
In my opinion….the boat already sits pretty low in the stern, maybe try to move some weights around to offset the fact you want to move the live well to the stern cooler boxes.
Cool idea though! Hope it works out for you.
Here are the switches and *original positions* on my 2006 222. Sorry the pictures are cut up..."switches 1" reads from left to right & "switches 2" reads from left to right as well.
