I mean it'd be cool if some dead IP's that are worth bringing back wound up in the hands of some passionate dev team looking to do just that, but the "Should" part of your title throws me off. If it had been "Would it be nice?" I'd say sure, but it makes very little sense to give up any IP's so they really shouldn't.
The main issue is that there's no real incentive to give up a dead IP as it may one day be in some way valuable, but by virtue of being dead they generally can't expect much compensation for it should they be open to selling it. That varies by IP, of course, but it's true more often than not.
