Your bags are great! I flew on small planes over Thanksgiving where all roller bag carry-ons were green tag checked - that's where you wait and pick up your bag on the jetway. I had one extremely tight connection and didn't want to risk the carry-on wait, so I packed my smaller purse and other essentials in a large tote. It worked great! If it fits under the seat, it can go on the plane carried by you. Your bags would be perfect for that purpose!
