My guess is Sectional 24 will stay at the 7 remaining teams.
Pike Central, Southridge, and West Vigo were all close to the bottom of 3A. Within 10 or so students of dropping to 2A. So that could change things as well. I always felt like both SR/HH were a package deal for sectional alignments, so just HH might get pulled back to SW IN.
But a safe assumption would be West Vigo moves up to 28 to replace Chatard should everyone else stay put.
