Trapout and Cool Weather Question

Got a tree with a bee hive in it and the owner wants them gone. They don't want the tree cut at all (one of the biggest beautiful cedars Ive ever seen) so I figure they have two options - kill them in the tree via can of Raid\Exterminator or let me trap them out. Obviously I am going to try to convince them to skip the can of Raid. The problem is that it is only in the 50s to 60s (daily highs) now so trapping with a bait frame of eggs I think would be out (too cold, dead eggs). Assuming I can't talk them into waiting for warmer weather before picking up the can of Raid, what are my options?

This will be my first trapout so I am green here. I was thinking I could bait them with a hive that is either queenless and has a couple of frames of brood/eggs WITH the bees on them. This would at least keep the brood/eggs alive until the bee tree bees join to help. Or use a weak queen right hive and use the tree bees to reinforce it. But I would think that the queenright hive idea might jeopardize the queen...yes??? With the queenless option, would the bees fight/kill each other or would the trapped out tree hive bees be welcomed with minimal fighting?

Any other options I am missing? Any help or ideas would be appreciated, thanks!
