Well I was thinking of this rule:

[G13]
Basketballs may not be intentionally placed out of bounds. Basketballs that inadvertently exit the Court will be placed back on the Court approximately at the point of exit, at the earliest safe opportunity, by Court staff.
Violation: Foul

Worst case, you launch it over the other end or side of the Arena and the Ref calls you on it. It depends on the interpretation.
