Topping and fim are techniques for veg, in flower all you will be doing is stressing the plant.

And like a couple of people have mentioned, before you try and veg the plant to the ceiling, consider the lighting you will need to illuminate these extra tall plants. Not much sense in vegging to the point that your lighting can't reach the middle and lower regions of the plants.
