I already have one of those, why not something like a valve stem
Most valve stems would be a bit shadetree and require valve removal to service unless valve permanently removed and cap capable of sealing stem is installed.
You can still drill and tap your T for a NPT petcock of your choice.

Do you know what the original T's threads are? I would like to know the tap/die size needed and may be helpful as you suggested, to others in the future. So far have found none in my sets to match. Thanks.

At this moment, nope.
If you're referencing the auction I posted, I didn't take the time out to see if that was the proper one for the Disco. I pointed that out because you can get them to fit, which eliminates the need for the plastic one.
You can also get a similar plug for each axle fill hole instead of the plastic ones.
I do agree with the not. In this isolated case you be wrong.
Your photos may show that if you tap out the factory T a pipe plug may fit and you may be able to use a factory plug into a 1/4 pipe taped hole. Unless I mistook what looks like sealant for seeping coolant residue and corrosion it may cause you may need to use sealant when using the factory plug. If your examples don't leak in service or when testing they are still hobbled together shadetree examples.
The factory T and plug threads are straight, not tapered pipe. That's why it's primary seal is an o-ring. I'm waiting for shanechevelle to report back do to his access to tap & dies to verify.
