A new manager would have a pretty good situation to start afresh in the Summer as well.
The following players are out of contract this Summer - Woods, Taylor, Hoban, Logan, Devlin, Leigh, McGinn, Wright, Main, Anderson, McLennan. With the exception of Hoban (if he avoids serious injury in the meantime) and Wright (who is leaving anyway) I would let all of the rest go at the end of their contracts. Hernandez is still under contract but presumably he will also be moved on. That will free up a fair amount of wages for a new manager to bring in his own players.
That would leave the following as a starting squad for a new manager
Lewis
Hoban
Considine
Ferguson
McRorie
Campbell
Ojo (I would pay up his contract in the Summer so he can find a new club)
McGeouch
Kennedy
Hedges
Hayes
Cosgrove (ideally will be sold but depends on him scoring a lot more goals before the end of the season)
That's not the worst basis of a squad for a good, ambitious manager to build on if he can bring in 10 or so new players to replace those that we would let go
