Cooler Mount for NRS Fishing Frame

I've got the NRS fishing frame with the curved front "angler seat". I have been trying to figure out a way to mount my yeti 65 in between the curved front bar and the curved foot bar. I attached an image for reference. Wondering if anyone has any ideas or if the actual NRS cooler mount/dry box mounts would work for this? It seems like you need two straight bars for those to work? Also was thinking about just using a dropbag, but just want the cooler off of the floor.

Thanks for any...
