The biggest issue with changing an effector is heating up the hotend to be able to pull the bowden tube out and not burning my fingers in the process ;).
For the sake of your fingers, buy a length of PTFE tubing for each of your hotends and detach them at the cold extruder end. :)
I'm thinking about putting a mounting plate next to the cold extruder motor with the plugs for the hotend secured to it. That way, the cable umbilical follows the same general path as the bowden tube, and the weight of the connectors are "sprung weight" (to borrow a term from race car suspension design) attached to the printer frame and not the moving effector plate. Any mass that is removed from the effector plate for reducing momentum is a good thing, IMO.....
