Only one way to find out for sure. On the plus side your side biz is plausible. On the negative, you have a bunch of cards with them already, and if the monitor scores are correct, you are on the line. I'd mentally have decided which one you could live without if they ask you to trade.

At the end of the day, the worst that could happen is you waste a hard pull. You can justify the reason for another card by saying you need to isolate your business spend to track your finances.
