So I applied on a whim, figured why not give it a shot, got the 30 day mail notice, and then a voicemail this morning from the fraud prevention department asking for additional verification. After some bouncing around their system, it turns out they just wanted to confirm that I'd applied for the card and the representative processed the application right then and there. So evidently Chase seems willing to exceed that overall $75k credit limit at this point. I'd previously had to have credit reallocated from another card to the CSP I'd applied for.

Unfortunately it's only a $6k limit, but maybe I can either do some cycling or call in to see if they'd let a one-time huge charge go through.
