The alternative is a 4O3A filter just for the tribander to provide a
separate feed for each band and a set of monoband low power filters
(e.g., the 5B4AGN kits) between the exciters and amplifiers.

There are multiple options for SO2R controllers - you need to be able
to switch a single set of headphones, mic, PTT, CW and potentially FSK
between the two rigs.  On the "simple end" is the microHAM micro2R,
or TopTen DXDoubler ,the YCCC box is middle of the road, and the
microHAM MK2R+ is the "high end" with built-in sound cards and basic
station automation functions.
