Yes they should be good. I’ve moved crocuses from the ground into pots, and also from pots into the ground, when as @Mr. Vine Eye says the flowers are done and the leaves are still there.
If you move them now, be careful not to disturb the roots by taking as much soil as you can. If they start to fade more quickly, that's the risk you take. They'll be fine next year. Birds like to peck crocuses, so you may find them easier to protect in a pot. Personally, I'd follow the advice above and move them when they have finished flowering (they don't last long).

I've dug mine up by accident multiple times, just popped them back in the ground and covered over, they've always been fine.
