Personally, I would advise against it, unless you own or have sole access to the land, for the reasons expressed above.
Even then, we hunters spend thousands and bleed and sweat each summer/fall to make blinds that blend naturally into the surroundings.
Nothing looks more like natural cover than, well, natural cover.
On several locations, I've simply taken in a piece of plywood to afford better footing behind good cover. Wear a face mask and move slowly if at all when birds are working.
If the pothole's surroundings aren't condusive to this, I agree with the others on matchng the cover with your blind.
I would add that it's good to gather your limbs, cattails, cane etc etc. some distance away from where you will be hunting. Otherwise, you can honk up your entire surroundings.
Avoid the box look, even if that means to simply add extra cover at the corners outside the blind to break up the sharp angles. There are no 90' angles in nature.
