You got the chart to reference already, and I'm just eyeballing that as maybe a 90mm stem.

If so, an 110mm / 35 degree stem would put the bars just shy of 3" taller and at the exact same reach as a 90mm/-17 degree. Looks like that's probably a 6° or maybe 10, so the change should be right around 3". Oops, NM. I was counting from the -17. So yeah, still shy of 3", but just shy.

There are a couple of different vendors to choose from to get that part.

Here's one.

You're in luck that you've a 31.8 clamp bar to work with, which gives you lots of MTB stem options.
