Christmas in July: Overlimping with KJo in the CO

At Christmas in July at MGM Springfield, the cardroom fills with loose-passive fish. In preparation for the game, I made this post about whether to overlimp with hands like KJo in late position. GG of course advised limping, and some agreed. More seemed to agree with Mlark that one should raise KJo over limpers.

UTG, LJ, HJ, and blinds are all loose passives. Button is tight passive. 1/2. Effective stack sizes are 150-325.

UTG, LJ, and HJ limp. Hero with KJo in the CO?
