Why are you limiting the consideration to receive?  If you have more than one rig (i.e., transmitter) in operation with remote switches controlling which antenna goes to which rig, how happy would you be with 45 dB isolation (or less than 30 DB in the case of the RCS-4)? Even 100 watts relative to a dBm is 50 dB.

Does this mean if you have one beam aimed at the Caribbean and one on Europe and only the EU antenna is selected, you're still receiving stations on the Caribbean beam but 45dB weaker?  Is this an issue?

Stackmatch. 45 dB @ 14 MHz. Hmmm.
