So, I can understand you need the Zinwell switches, to respond correctly to the 11/15V for Hor/vert (and I guess also 0/22kHz to chose between 124E and 128E?).
The Zinwell switches, being receiver-fed, never supply more than 11/15 Volt on the LNB-inputs I guess.
And the Zinwell switch is made to feed not just the 11/15 Volt (or 13/18 Volt), but also the 22kHz, to the (quad or monoblock) LNBs.
(You're not using the flexports, right? I'm not sure how they work -- these inputs are not really explained in the manual, alas.)
However, when you fix external powering for your LNBs, you're not dependant on these features of the Zinwell switch I suppose.
You could have dual output LNBs or quatro output LNBs, with DC-blocked splitters connected to your Zinwells.
Many quatro LNBs can be powered by any (only one!) of their four ports; I've seen that tested.
(For some, even 11 volt might even be enough? I remembe vaguely reading a JULTEC presentation of LNBs needing only 9 to 10 volts; but I might be wrong.)
And I believe the 22kHz doesn't affect the quatro LNB, as it doesn't have an internal switch that wants to react to it. I don't remember reading much about that though, but I'm not into multiswitches, so that is not strange.
So I would think that with external power supply (or possibly even without?!?), you wouldn't need the (modified) monoblock anymore, or the 0/22kHz switch to eliminate the 22kHz.
So the simplest solution for you might be, to change the modified monoblock LNB, and see from there. The DC-through splitters might again be usable, then, when trying without external power.
And the LOFs in the receivers should probably be altered, of course.
I don't have multiswitches or quatro LNBs though; cannot test it for you. (And I am totally unfamilliar with dual output KU-LNBs.)
I hope my reasoning makes sense to you (as I was still thinking, while writing this post...).
