Anyone use something like this as a sump?

I have a few I use for water, RO & Top Off, & water changes.
Keep in mind those are usually formed to stand not lay flat.
There are some made you could use but they will bow & you will have to find a way to remedy that.

These will bow? I figured, but how bad is it?

I would not use those as a sump..
seems overly expensive, not see through and would be difficult to bond baffles to it if you wanted to do that as polyethylene is more difficult to bond too compared to acrylic or other plastics.

They are fine if just a tank. My buddie did one.
As stated they still bow & need a frame.
And as mcgyvr says good luck with modifications.
