How are you going to tune it?

ps - I love the compensation

pps - I would ramp the slots as much as possible to get better break angle

That's enough strings for your next three guitars.

Don’t use a slotted peg head or no one will ever change the strings.

Avoid a WRC top or you will be regluing the bridge until the cows come home......

You know too that folks like me charge more to do 12's. This one is going to cost the owner a bundle just for a string change...;)

Consider a decent chorus pedal and nix 12 of those strings.....;)

Horrors!
I sure wouldn't use anything like Engelmann or rosewood on a guitar like that! It would never stop ringing...
You will need a rather thick top and notice the saddle is almost flat to the bridge top. That suggests an "out of whack" neck/bowed top. There is no break angle to speak of and it looks like the 18th and some of the rest of that course probably rattle more than make a note...
Hope you got fat fingers!

You could reduce the number of pins. People successfully make bridges with 2 strings per pin - 6 pins for a 12 string. 3 strings in a hole would probably be pushing it, but you could definitely get away with the 2 thinner octave strings sharing the same hole. That would reduce weight, clutter, complexity.

I would be concerned that 18 holes in the top and bridge plate means they are becoming a lot like swiss cheese - floppy and crack-prone. Combine that with the increased string tension and you have a recipe for an unstable soundboard. This might be why that one has developed bad geometry and needed the saddle lowered by such a drastic amount. Yes - and definitely not cedar for the top. This thing needs the stiffest spruce that you can find.

I would explore some sort of pinless bridge system. Then again, I wouldn't want to build such an instrument, so ... idunno

Build it with a tail piece and an adjustable neck joint.

Actually right now as we speak, er write, there is a guy at an electric guitar forum who wants to build an 18 string - 6 courses of 3 strings - baritone electric with a really really weird tuning. He claims he has a "luthier" helping him, I told him he is going to need a lot of help. Since you are an electric builder maybe you'd like to chime in.

That's what I thought. There are a number of very courteous cautions to what appears to be an honest question.
