Hi, all.

I want to replace the CVT and clutch with an infinitely variable transmission. I'll control the gear ratio via a twist-grip on the left handlebar.

Nuvinci has their 43mm Delta series, but they don't sell to the end consumer, only to OEM manufacturers.

So... anyone know how I can get my hands on either a Nuvinci Delta or similar?

You can try writing to Nuvinci stating you are developing a new scooter, and would like to purchase one of their developer's kits, or at least one of the hubs you would like to experiment with. The key is brevity, those developing new things do not give tons of details, only enough to get what they want. Use the KISS rule.

I did similar when I needed a glass actuator with almost zero friction for a stirling engine design I've been working on for years. The manufacturer ended up sending me one for free, hoping my design would be a success and lead to large orders in the future. All I told them was I was working on a design project that required a part similar to the one they carry, if I recall it was one paragraph with no details beyond what I required.
