Reapportionment's gonna be wild if this happens. A lot of states are going to be annoyed at losing/not gaining as many seats as they hoped for.
I mean, Texas isn't going to mind getting 38 rather than 39, but Montana will definitely mind getting 1 rather than 2.
Reapportionment should happen before PR is added. At the very least I expect Democrats to moderately expand the house size by a bit to not piss of any state/delegation.
Yeah, expanding it to 440 (4 for PR and 1 for DC) would be the best solution imo
