The only issue I see is that to get the most mileage out of Dair we need to start it early in the jump. This makes it really 50/50 read-ish instead of a reaction type situation that occurs out of Sheik's Dthrow, for example.
I think mixing it up with SHAD is pretty solid, as most responses to Dair would be to swat us or to run away, and SHAD is nice and non committal (movementwise) such that we can adjust our trajectory to match what they do in response to the hop.
It's also worth noting that you have to be willing to eat some punishment during the conditioning phase here. Dair is still punishable on block, especially when the opponent knows how to deal with it (spotdodge the end). However, we're heavy and trades are generally okay, so it's not too big a downside in general.
