Like TRENDZ said, Ford has coils that fit into the Gen II spark plug tube. The ones I was looking at were Coyote specific. 2011-2015 5.0 Coyote coils seem like the best for repurposing. On 2/24/16, Ford changed the electrical connector on the Coyote coil to a different style. Most aftermarket COP applications (FAST XIM) come with the earlier style connector. Take a look at: https://www.summitracing.com/parts/msd-82488

These coils are about 3/8" too long to be a perfect fit. But they have a stainless steel spring that compresses against spark plug electrode at the top. There is no "click" when the coil is pushed onto the spark plug. I trimmed off ~3/8" from the coil boot where it slips over the top of the spark plug and test fit everything. The connector spring in the coil is like 1-1/2" long so it just compresses a bit more. Works great. I then connected the coil to a battery with a starter motor bump switch and triggered the coil a few times. There was a nice fat spark.

I see your nice polished cast Gen I valve covers ... if they use the same dimension spark plug tubes as the Gen II, you would have to figure out how to run that spark plug wire cover (like in Twostick's picture) that would hold the coils down against the plugs and hide the fact that you're running COP. And you better check into the rules you mentioned. If they won't allow EFI then they probably aren't going to be real happy that you're running COP.

Here's some clicks of my research:

Also you need to be aware that there are “smart” & “dumb” coils when doing combinations of components. Whatever your choice of controller is, will dictate what coil you can use.
Generally speaking, two wire connection on the coil is “dumb”
Any more than two wires are “smart”.

Joel, take a took at these.

You'll have to get by the Brand X label, but this may work out. There more that show up at the bottom of the epay page for me.
