There is already a way to get the same effect but with one amplifier... I have a SPE-1K amp integrated with my Flex 5000 (with sincere thanks to Steve K5FR for his work on dduti to add the support!) - once the amp is programmed, it is possible to instantly move from one band to another and transmit.
The amp takes care of which antenna to use, automatically selects the correct tuner settings, and responds to the PTT - single Flex 5000. When I was considering which amp to buy, I looked at both the SPE and the ACOM 2000 - for me the SPE won over because of 6m support - other's mileage will vary! With this solution, you can configure the amp on one of the antenna ports for the Flex, then use either the RX2 input or a different antenna port for routing the second band receive antenna to RX2. This is simplest with a dedicated antenna for receive on the other band - external switching is needed to support mapping a non-dedicated antenna between the amplifier antenna ports and the RX2 port choice. If band pass filters are used, the external switching is likely already in place. Although I haven't tried SO2R yet, I think the easiest way to deal with the software integration would be to use the VFO A<>B selection - map TX to always follow VFO A - VFO B is used for RX2 on whatever band for listening. When you want to transmit on the other band, flip the VFOs - make the contact and then flip back. Rudy correctly points out the requirements if you are using non-auto tune amplifiers. Hope this helps!

The real issue, however, is not the ability to listen on 2 bands, but the ability to transmit on 2 bands, one after another, with different antennas and amplifiers, without upfront assignment of bands to ports.
