Yes it would be expensive for sure!
The large size of the Polaris panels would mean extra expense since
area strongly drives costs for board/flex manufacturing. In general
flex is 1.5x the tooling charge of a rigid PCB.

For now, manual panel drilling and replacement is far more economical
(~2.5hrs labor and $70 in switches). With a hot tweezer, I was able
to speed up the process. I don't have access to a $2000 wire
cutting/stripping machine, but with one it could be even faster.
