JKB, definitely. The question that I cannot answer is how much more GPM would it take to keep it full?
That is a pretty big question too! Any way of testing this out before you sink a wad of cash into a new well?
Not sure what your current well is, but maybe try a booster pump inline to get more gpm for a test?
I know how you feel tho. I've been beating my head against a wall for several years now on the best way to build a pond in my situation. Prices are pretty steep, no matter which scenario. Heck, the small 30' x 80' x 8' deep special purpose ponds I wanted to do are rolling in at about 10K each. That's DIY, with cheap help!
