Have a flight tomorrow (Feb8) CID->ORD->BZN

CID -> ORD 751a -> 915a. -> Landing at gate M7
ORD -> BZN 1000a -> 1228p -> Departing from H4

Why are domestics on the CRJ 2 landing in T5 now? And going from international terminal (T5 gate M7) to T3 (H4) seems impossible in that short of time? Would agents be receptive to changing departure airport to ORD and me making drive to ORD in the AM instead? Or am I just screwed on this one?
