I have LP-PAN working with Skimmer in Softrock-IF mode but the 24 kHz
bandwidth limitation is frustrating.
Rich this isn't an answer to your question but just an observation FWIW. I
bought LP-PAN immediately after it came out (beta #0008 I think). I got it
working with HRD and PowerSDR but soon discovered CW Skimmer would work
directly in Softrock on IF mode with Skimmer's OmniRIG interface (no HRD or
PSDR needed). I much prefer Skimmer's waterfall to PSDR's but, like you,
thought the 24 kHz limitation would be too limiting (and I still don't fully
understand why Alex does that with the K3).
Nevertheless, after using this setup for a couple of years, here are my
observations for my two normal uses of Skimmer:
1. Contest SPing. Although Skimmer limits spans to +/- 12 kHz about the
RX frequency on VFO A, it continually shifts this window as you tune up or
down the band. For SPing in contests using Blind Skimmer (OK for
unassisted categories) this isn't a problem because I'm usually tuning up or
down the band sequentially, so there are always decoder dots in the window
above or below where VFO A is set.
2. Working massive split DX pileups using the KRX3. I lock VFO B to the DX
station's frequency and then use VFO A for the pileup (and placement of my
TX). In this mode I use Skimmer's 599 function to identify the last
station worked and click on 599 to send my TX on VFO A there (or with a
slight XIT offset). I've not yet encountered pileups wider than 24 kHz so
the window about VFO A has been entirely adequate.
Of course 24 kHz doesn't give you a complete picture of CW bands but in
practice I haven't found that to be as much of a problem as I first
imagined. I also have a P3 which can be used for the big picture but I much
prefer Skimmer's waterfall because of it's more accurate VFO placement and
more elegant K3 integration (see video below). I use AutoHotKey with N1MM
to allow tuning with a mouse wheel so I can very rapidly jump from one
station to the next (without losing N1MM focus).

wheel incrementing)
I'm still hopeful Alex will someday increase the 24 kHz limit (at least for
the K3) but until then Skimmer, even with the present limitations, meets my
needs outlined above.
