This all assumes that I am dissatisfied with my current plan. I like making
my own boards, and having the layout in Kicad isn't going to make the
transferring any better. Plus, I hate soldering professionally made boards
with solder mask etc.
As far as "never having to drill fibreglass or cut jumpers ever again,"
well, it's all just a part of DIY. I like DIY, all of it, even the crappy

Just tossing this out there DGD,
KiCad takes about 3-6 hours to learn while doing your first project.
There's tutorials that will go through creating schematics, custom symbols,
board layout, routing and even custom footprints - everything needed to
Judging by the amount of components you mention here, it's of medium
complexity. Board layout and routing could be a bit more involved, lets say
10-15 hours if it's your first time routing things. But you already have a
layout that works for you to copy..
I know I'm not the first smart-arse that has tried to convince you that
Excel isn't the best tool to use for PCB layout, but after reading your
breakdown of time here... I'd learn the program just so I never have to
drill fiberglass (tell me you have adequate dust collection in place?
and cut jumpers again.
There are places that will place SMT components for cheap/free on the board
and you could just leave the hand-soldering for your hand-matched and binned
components. Grand total time could be under 2h - 3h savings per board, not
to mention the fact that your troubleshooting will be greatly reduced.
Learning Kicad pays for itself in as little as 3-4 units.
If you're still super interested in never learning it, you likely have some
customers that are fluent in KiCad and would draw you up a board in exchange
for a few free units.
