That is a seriously strange way of doing what you want.
That flexplate center thing you machined looks iffy. What is up with the big oops groove cut into the face? Are you a machinist or a hobby guy with a lathe and a mill?
When flexplates fail it's usually in the high stress area right where you put your weld. Welds done by hand are a bit iffy for stuff like this. Flexplates are rather intolerant of thickness changes like that. By design, it flexes, and flexes differently depending on load and line pressure (converter is basically a metal balloon).
Hope it works, but you have gone down a misguided rabbit hole IMO.
