No problem. I used to do home remodels for a living. Could always tell when sizing was applied before the paper or not.
I recently took down some paper in my own home that I put up years ago (with sizing underneath) and most of it came off in full sheets. All that was left was thin spatter of glue which came off easily with sponge and water.
Also might be of some help, if you are going to texture before painting, most of the time a good mud man can fill those places that you are scaring while he is texturing.
EDIT That's if you go with a hand troweled texture. If a roll on texture or no texture at all then it would have to be smoothed out.
