Personally I think texturing would look like just exactly what it was- covering up a problem.
Take a stiff putty knife and scrape off what you can. Then do some more. The more you get off this way , the easier the next part. Do not gouge the sheetrock- that causes more problems.
Using premixed topping like Plus 3 , and a wide mud blade -12" ( also have a 6" to get it onto the big one and help to work it) skim what unevenness is there.
Let dry. Sand smooth ( use a light to the side when sanding to see)
Prime mud- look over again- spot what ever needs it, resand those and spot prime, paint 2 full coats.
This is done all the time to fix surface problems.
Good luck!
