I take it you are running two receivers? Seems to me a software solution is
possible.
Do we need to do any more than just average the two? In your example doesn't
look like time delays are needed for steering.

Having used diversity reception techniques as
far back as the 70s and knowing it was used in
the 40s to improve RTTY reception for mil comms,
that improvement is possible.
An early technique used 2 coherent R-390As and
dual fsk demod unit. The antennas were often
of different polarization
”,
sometimes with a considerable improvement in S/N.

I have been messing around with WSPR decoding on 630m with a pair of
phase-locked receivers and two receive antennas.
I have put together some software to save two sets of coherent samples
for each 2-minute period, and then after the fact I can combine the
two sets of samples w/ a configurable
