I see several suggestions already, mostly involving building circuits. That is fine if you wish but you could also just connect together the key lines, using diodes to isolate them from one another, and making sure you respect the current and voltage ratings of the key line. Both amps will of course key but most amplifiers have an off switch or standby facility and unless you are using 6m and HF at the same time it is probably easier just to disable the unused amplifier.
