Convert DT 125 R to Supermoto?

Good day,

I want to convert my Yamaha DT 125 R to a supermoto. I'm facing the following problem:
I can't find any suitable Supermoto wheels for my DT. Does anyone know if there are other Yamaha models whose wheels I can use without any problems?
Alternatively, I've considered using the original wheel hubs and lacing them onto a new rim. However, I'm worried about finding the right spokes, etc., to fit the hub.
Does anyone have experience with such a conversion and can help me?

Ps. I don't want to know whether it's financially worthwhile, etc., but rather what options I have for such a conversion.

Thank you very much for the answers.
