I did something like that. But, I used Velcro instead.
Then if I need to adjust things for more packing I just remover the panel and replace it when done.
I did the same thing in my left bag as Duey.
I have 2 longs strips that run about 3/4 the way front to rear.
And a small piece of wood with a strip on the bottom of it. I can attach it straight or any angel that I need. If I don't want things sticking to the Velcro, I have a piece of plastic the same size as the bottom of the bag I lay in there... Yeah, I know overkill, but one day I didn't have nothing to do except twiddle my thumbs....
Right now it is holding some tire gauges, my 'D' wrench for the carbs and another piece I picked up off the highway. Think it is off of a HD, but can't be sure.......
