2-6 door rough opening tolerance?

I'm adding a closet.under my stairs and I am trying to make the rough in for a 30" door. It's a really tight space and I essentially have to attach my jack studs directly to the outside wall studs. Unfortunately this leaves me with a rough opening slightly too large, and a little cattywompus.

From what I found only I am aiming for 32.5" wide rough openning. My current situation would leave me with a rough opening that is 32.75" wide at the bottom and nearly 33" wide at the top. Is this too far out of my target for shimming?

I think my only other option would be to reframe the entire section, which wouldn't be crazy but I would really rather not.
