It would produce both balls and hybrids but given the shape of the wall hybrids and the pure balls it would be easy to tell which is which and if any are iffy I'll just keep them. Theres alsothe matter of the ball python sire's morph which could also help in "sniffing out" the pures as opposed to the hybrids. The walls are also more striped so as long as neither of the parents are that striped it will make it easier to tell to. The part about making it a mixed clutch is to reduce the slugging rates and produce more babies. One again, all that are not definitely one or the other will stay with me or someone I know well that understands not to breed it and that it may be a hybrid. The not breeding is to ensure that no 1/4 woma 3/4 balls are sold as pure balls or anything like that, assuming walls are viable. For the most part hybrids are pretty obvious, especially with things like this. With hybrids like angry balls, however, they could easily be sold as a new morph and no one would even know it unless it looked more ball-ish but had the beaded scales or the other way around. But walls look so much unlike a pure ball that there's really not much of a risk of misidentifing it as anything other than a wall. And one egg can't be double sired.
