I shortened my oil tank also, as did a guy in California. The firewall was made per the plans. I only removed the round portion on the bottom, so there were no changes to the pickup tube or the screen.

The original tank was shorter by a couple inches to accommodate the round cowl. otherwise the oil door on the top won't close. The tank ends up crushing the electrical braid on the back of the engine. The new tube in the lid is going to have to be shortened as well, it goes the full length of the oil tank as does the screen.
I like the placement of your modules. Did you have to lengthen the plug wires or did you use what you had? I"ll check on it today and start the fabrication process. I am going to have some help here for a week so I think I can get er done when my buddy arrives. He's an airplane guy from Alaska and pretty much works for food when he's on my place.
I"ll send some pics as well.
Are the early and late oil tanks a different length,also shifting the modules away from heat and vibration to the cabin side of the firewall can only be a good thing.
Why not use your old oil tank ?

The old tanks and new tanks are all the same hight. The Model IV round cowl had the tank shortened due to the tight space of the cowl. It reduces the oil quantity a minuscule amount.
I want to use the new tank because it has an upgraded hose connection to A/N fittings and I like the fact that the inlet and outlet ports are on the lid. It makes identifying a crack or failure easy and and easier fix than pulling the tank.
It looks like I will need to get longer plug wires and sheaths to move the CDI but I agree, moving it is the only option for lifespan of the part. Here is a picture of the tank and you can see that I need to shorten the rest of the hardware associated with the tank.
when I changed out my engine, I sent the tank to John and he fixed it up to the right height for me. I also updated to the new motor mount and new muffler. once I had everything put together on the new motor mount and mounts I went to the airport and swapped out engines in about an hour. easy very easy.

I finished the tank tonight. It took about an hour to trim the extra length from the intake tube and trim the screen. Then I cleaned everything to make sure there was no metal shavings or screen material where it shouldn't be. I'll re organize the spider tomorrow for a good position on top of the engine for the tank.
