Sorry, I don't have a rise number for you, but we had the same trouble with ds. He outgrew the rise of his 1's L--O--N--G before he had even time to grow into the waist
He was still easily on the crossover snaps when he outgrew the 1's.
So....
I sold all my KL 2's (I had bought like 30 of them
: ) and changed brands. My kiddo just wasn't shaped like a Kissaluv anymore. He is long and thin with a higher rise and thunky thighs.
Let's see...some brands of available diapers that I would say have a higher rise:
Sugarpeas (especially the side snap)
Ecobaby Absorbitalls
that ecobaby diaper with the velcro, don't remember the name
Happy Heiny's, but bf poo can leak out of the legs of those if they don't fit just right, and your dc is about to get to the age where they slim down, so that might be an issue
Harleez
I'll try to think of some more
