Pool beam and coping stones comes up too high - see pic. Can I remove coping stones and cut the beam down to where I can do stone coping flush with pool deck or maybe just a cantilever concrete edge without compromising pool structure integrity? If it will compromise integrity, then will I need to redo the pool beam lower to achieve this effect or something else? Thx! Oh and I can't raise deck to level of coping otherwise it would be above side door entry to house.
