[Elecraft] Sharing KPA500/KAT500 with K3S and KX3?

[K1dj]

I will be using my new KX3 in place of my ailing K3S while the latter is en route to Elecraft for repairs.

In addition to running the KX3 barefoot, I would like to run it into my KPA500/KAT500.  Is there a good method, plug and play or otherwise, for (a) hooking the KX3 up to the amp while the K3S is away, and (b) sharing the amp between the two rigs once the K3S gets back from Watsonville?
