I'm optimistic that you'll get the CIP.
A lot of times I'll read recon stories that go like, "can you reconsider my application by not counting the AU cards?" "Nope." End of story. Whereas, in your case, divorce is a pretty darn good reason to disregard your ex's cards on which you happened to be a removed AU. I think sending your app up the chain is just a formality. Fingers crossed for you! And keep us updated!
DO NOT apply for another Chase card until you find out about the CIP. For approval, as a Chase business card, the CIP requires you have had no other Chase applications within the last 30 days. You wouldn't want to apply for another Chase card while the CIP is still pending, and risk another card application being the reason you were denied the CIP again. When you find out about the CIP, you can either (1) apply for another personal card (like the CSR or CSP, but not both) within 30 days of the date of your last Chase application. You can be approved for a Chase personal card as long as you have less than 2 Chase applications in the last 30 days (which would preclude a double dip because that would take you to 3 applications in the last 30 days). Or, (2) wait 30 days from the date of your last application to reapply for the CIP, or double dip the CSR+CSP.
Remember that the CSR and CSP are also subject to the 5/24 rule. So if you were denied the CIP because you were over 5/24 with those AUs, you'll likely be denied for the CSR and/or CSP because of 5/24 too, unless those AUs have been removed from your credit reports or aged past 24 months.
