Yes but, taking just two lambs away ... will they be on their own? Having only two young ones together they may fret more. I would be tempted to wean all the lambs in one go, so that they feel like they are still in a flock, so to speak. You can put the ewe lambs back with their mums after a couple of weeks.
An alternative would be if you have a next door field that they could go in where they can still see their mums through the fence, then they will be reassured by their presence.
