Straighten heavy pine door

[treppan]

I've got a set of pine double doors that open into a room, but over time the wood has warped and then no longer meet correctly in the middle (one of the doors looks like it has been twisted slightly around an axis of opposite corners). They're painted white in satinwood.

Is it likely that I could get these straightened somehow, either by inserting a couple of rods through it or getting it pressed under heat?

I guess I may have to make do or replace, but perhaps there is something I'm not aware of.
