I've been trying to come up with a cart for my 26er and just haven't found the right set-up.
My first kettle was a Performer with the flip up table and I loved how sturdy it was and how compact it was when not in use.
I always felt crowded for cooking space on the 22 so I found a used 26er and love the room but I miss the side table and it just doesn't feel as sturdy. Then I came across this cart for a BGE XL
https://smokenproducts.com/product/the-cuna-xl/The BGE XL outside diameter is 26.5" so diameter wise it should fit, my only concern is that there may not be enough room to remove the ash catcher - but I guess I could always cut those bars out if they got in the way.
