Good info.

Do you know where to buy some stater plates, 80-90mm, 12 tooth?

Not that size but www.gobrushless.com has 18pole 65mm stators. Stators that size will always have more than 12 poles, otherwise the teeth would get too massive:

Scorpion (via www.innov8tivedesigns.com ) will be producering +100mm stators later on.
