10 excess sets of center seats 5 old config in and 3 new config out
So, one Hawaiian could be converted needing 4 sets of windows and 3 seats of center seats.

The question is if the rest of the interior on the current Hawaiian units will match the new 2 class aircraft. There are lav changes at door 3 and left side of door 4.
