The stretchers are warped badly and have to be replaced.

I'd joint and glue. Dowels almost always indicate the joint was
originally glued.
I'd also think about trueing the stretchers with a hand-plane,
but that depends on how bad the warp is. Obviously, you'd want to
retrofit
the stretchers with some provision for wood movement, too.
