I want to say I've read this story before (or lots of similar stories) in this very thread, so yes it's doable, but may be harder for you than OP.
The big reason being OP signed up for the Chase Sapphire Reserve when the signup bonus was still 100,000 Ultimate Rewards points per card, and OP and SO each got a card for a total of 200,000 UR points. In March, Chase decreased the CSR's bonus to 50,000 UR points per card, per 24 months. So if you and your husband were to both sign up for the CSR, the best you could do for the combined bonuses is just 100,000 UR points. The Chase Ink Preferred has a big 80,000 UR points signup bonus per card, so if you and your husband don't sign up for this business card, then you two are out a combined 160,000 UR points, plus whatever points you would've earned from meeting minimum spends. So just from these two caveats, you are running behind OP by at least 260,000 UR points. A UR point is worth 1¢ in statement credit, but when you redeem UR points through Chase for travel like a
Disney cruise using your CSR account, 1 UR point is worth 1.5¢. So those missing 260,000 UR points equate to $3,900 that you have to make up somewhere else, if not in cash. There aren't many Chase UR cards left with a big enough bonus.
I don't know the status of your husband's Chase Sapphire Preferred, like when he applied for it, whether he hit the minimum spend to earn the 50,000 UR points bonus. I also don't know your and your husband's credit card histories, and most importantly how many new credit cards you've opened in the last 24 months. Chase has a rule to automatically deny credit cards to applicants who have opened 5 or more credit cards from any issuer in the past 24 months (the 5/24 rule). So before you start applying for Chase's UR credit cards, you want to be sure you are under 5/24 and have enough slots open to get the UR-earning cards you want to get. You may also want to have your husband remove you as an AU on the CSP and have the removal reported to the credit agencies because that could appear on your credit report like a credit card account that counts against the 5/24 rule. Then your husband should probably send you a referral to apply for the CSP, because if you're approved for the card, he earns 10,000 UR points for the referral and you can work on the minimum spend to get the 50,000 UR points bonus.
I'd note that the OP seems to be talking about using the Barclay Arrival+ to wipe out some of the remaining balance. This is worth considering if you're over 5/24, because opening this card under 5/24 would take up a slot that could go towards opening a Chase card. The Arrival+ comes with 50,000 bonus miles after spending $3,000 in 90 days, which is good for a $500 statement credit, plus at least another $60 credit in points from meeting minimum spends.
