Why not just bury the sump in my liner pool?

My pool is in a particularly bad area for ground water, the previous owner went through many liners. I know its bad, and during storms the groundwater can get higher than the returns. I know the right way to fix it is to dig sump wells around the perimeter, but costs are preventing that.

My liner is currently out and am following @jimmythegreek 's advice of a sump in the deep end to lower the water far enough to patch quickly and get water onto the new liner before mother nature can do her thing. I am also repairing my step, and have a section of concrete removed giving me an idea. Could a void (or well) be introduced under the floor that allows me to leave the sump installed, with the outflow pipe and electrical routed under the floor, under the steel wall rising vertically next to the step? Summer months, remove power and hose connection and cover with a skimmer plate. The void would have to be structurally sound to withstand the pressure of the weight above it. Non-freezing winter months it could keep pace with the groundwater coming in and provide relief during the storms when the level gets really high.

I figured this group would be the best to ask - crazy?

Could you put the pit next to the pool, rather than under it? I have pit next to my fiberglass pool that collects the ground water and a sump pump in there that pumps the water out when needed. I have the discharge piped to the storm drains and the electrical hard wired in. The pump turns on when needed and always keeps the ground water away from the shell. I do check the pump frequently as it is just a sump pump and could go out like any other pump.

You can see the big green pipe at the top, that goes down to my pit.

Yes - that is the right way to do it. Some day. It would require me to remove large sections of concrete apron to dig deep enough to make a difference. I was thinking exactly that when I had the idea to use the current large hole, which is your idea, but in the pool itself. Another problem I have is ~5 feet down is a hardpan, common in the area that has to be jackhammered - no way a drill could get through. I know this from the extensive other drainage I have installed on the property. I appreciate the comment, and had I been the one installing the pool ~30 years ago I would have integrated this.
Thanks.
