Can do; wouldn't recommend it: patches are NEVER as strong as the original material. That's especially true on the fiber-reinforced material Intex pools are made from.

Instead, why don't you wait till fall, drain the pool, take it down, and put it back up the way you want? The results would be much more reliable.

Or . . . just build a small enclosure, using wooden fence material and 5/4" boards? (Do NOT put the pump/filter in a non-ventilated 'dog-house'!)
