I believe the "change" you request is already available, it just takes
some understanding of the difference between Diversity mode and the
subRX in non-diversity.
When the K3/K3S is in diversity mode, the operation is just like a
single receiver - both the main and subRX work from VFO

I only have power-pole's on my K3/10 and KXPA-100.
I installed a power-pole on the CCI 140w linear I built, but would
not do it a second time. None of these power-pole will stay seated
if equipment is physically moved.
I very much like the power connectors used by DEMI on their
transverters
Seems a solution looking for a problem. In diversity both Rx are
slaved to VFO-A.
I use diversity on 2m eme to receive two polarities simultaneously
and can select Rx frequency up to +/- 45 KHz of the setting of
VFO-A. To transmit on the selected Rx frequency I operate split Tx
using VFO-B.
Checked the Elecraft site and didn't see any option to download a manual. Is
there one and I missed it? Only noticed the chance to download a data sheet.
Happy 4th to all.
