It is how I do it. Often scary, but so far I have not damaged one. Removing the balance from the cock and adjusting it on a bench block is truly safer. -

This much gap will make the rollers and all run too eccentric. The pin , the passing notch and the safety roller all have strict tolerances to coincide with the fork slot, gaurd pin and horns. Will it run ? Maybe, but it will restrict the escapement efficiency. -

Echoing Neven, the safety action on nice pieces is often very close, and a slight eccentricity can affect this. Runs great horizontal, then one or two verticals crap out. Without fail the balance will be above the escapement in these faulty positions- though sometimes also at horizontal to it, the "draw" (what pulls the fork to the banking) is often less than ideal, especially in older pieces and in my experience more with higher grade stuff. Suddenly the guard pin is rubbing. -
Failure! I attempted to pull the bad exit stone from one fork (came out without further damage) and then pull the still good exit stone from the other fork but it crumbled like sand. I had soaked it in alcohol about a half hour and all the surface shellac brushed away. Oh well. This one will go back in the box until I have another compatible fork; probably not going to spend $30 on a jewel. It was a bare movement from a junk box and nobody will miss it.
