Hey there Leliantu, The more you cut, less product you will have at the end. I see what you want to do but it's not necessary. first there is much more light when you close the tent than when it's open. Second it will give a shock to the plant and that's not good news at this stage in flowering. At the end, flowers and bud sites are not photosensitive, actually it's only the leafs that are photosensitive, so the more you cut the less light and energy the plant actually has. So the plant will focus on making more leafs , and it will reduce the quality of your buds. The best for you is maybe some light LST or just hold on and do your best until harvest, just go on auto pilot and pray. Next time, if you want small plants try to grow with clones, they stay really short so you can make more than one level even inside a tent. Hope this helps ! 🚀
