Not saying anybody WOULD,,,,,,,,,,, but if you COULD.....
parallel a pair of SB-220s on a single band ?
Wilkinson Power deviders / combiners for zero phase combining?
A 90 degree network on the input and opposite 90 degree on output ?
Run them in push-pull ( 180 degrees )

Assuming all splitters/ combiners would be made from coax.

Or, just use short runs of equal length coax and a coax tee for the inputs
and accept a 2:1 drive mismatch ?

Hummmmmmm
