Well, going to take everyone's advice.
I will leave the wire as is and can move the existing boxes towards the pool using it for pump and lights. That will actually reduce the draw on the 110 and keep me from adding another junction box sitting above ground.
The power company can run power to the shed. I will find a 100 amp box and get whatever I could want in the shop.
Last question, will a 100 amp box run a small ac, lights, power tools , on demand water heater and lights for a bath house? thinking ahead as others suggested?
thanks for all the good advice. Would not have come to this solution without all the input.
