I think this is a pretty good idea, I already had a problem with this once since the 24 update... Had a command pod under a probe, and even though I had emptied it previously manually, because of some editing Jeb managed to sneak back into it... So I had to complete my rescue mission by trading Jeb for the other stranded Kerbal, then go right on back to rescue Jeb (got a soft spot for him .)
