Adding baffling to a drag race fuel cell

I'm planning on using a generic 5 gallon aluminum fuel cell in my challenge build.  I am however a bit concerned that the foam in the cell will not be enough to keep fuel sloshing away from the sump during some hard cornering.  So, I guess the first question is, is that concern valid, or will it be fine?

If it won't be fine, I am trying to come up with a way to put baffles in the tank, that won't require me cutting it open and welding, since I am not setup to weld aluminum.  I scribbled up the idea below.  I figure using mostly 2" tall thin metal, I could cut and bend 2-3 pieces that could be inserted through the fuel filler, and bolted together from above.  It'd be a press fit, and would hopefully keep the pickup  from being starved.  The rear piece would be cut and bent to fit against the two rear corners of the cell, and would have some small cutouts to allow fuel to flow back in if the level got too low.  The piece going to the front corner would have a small segment as tall as the inside of the cell, to keep it from "floating" upward.  Any thoughts?

I had no issues with the generic 10 gal aluminum sumped cell in the 240z during autocross with 5 gallons in it. I feel like the 5 gallon being essentially the same height just smaller length/width that you will be plenty good with or without the foam. I took the foam out of mine because i didn't really trust it but have since run some in the wartburg and it did not break down in 2 years

Thanks, sounds like one less thing to worry about.
