I would absolutely want to try black crappie in a 1/10 acre pond someday, but I'd have one requirement. I'd want to be able to seine it.
I could anticipate at least once every couple of years to get rid of all but the best fish. If you can't seine you'll likely need to find other ways to keep the numbers in check. Maybe by eliminating cover, so they can't hide. Or maybe by angling the heck out of them.
I'd make darn sure that some kind of predator, be it human or fish, has really good access to the baby crappie.
