FWIW, I've seen it work out.
Girl on DD's team last spring was a few months into the switch. She was thrown/struck out most of the time, but by the end of the summer, 7 months later, obp was consistenly at or above .750, and she was starting to be able to hit with some authority, poking a hard grounder or line drive through when she came up with runners on(batted 1st or 2nd usually).
She did have a D2 slapper as a hitting coach, and team coach who knew enough to leave her alone, no matter what happened early on.
