It seems to me that this solution would tie the K3S++ to mains
power. Being tied to mains power would impact my club's use of
K3s with batteries on events like the California QSO party. (Our
location does not permit generators.) I don't know how much such
a restriction would shrink the K3S market.
A voltage booster could be a solution. Such a device would have
to be well shielded and bypassed to avoid RFI. It could either
be internal to the radio or a "bump on the power cable". Such
devices are available in the market and seem to work well.

The cause for this is the use of 12V finals. It would be much improved by
moving to 24 or 50V finals.
Move the /K3s II/ to 50V finals, say a pair of MRF 150's,
limited to 150 or 200W max output. Design/Sell an outboard 50V
switching supply capable of 15-20A continuous current, with a
10A 12V switcher built in for the rest of the radio.
