Do you think that Flash(summoner spell ONLY) should disjoint auto-attacks and point-click abilities?

So dota has an item called blink dagger that is the same as what flash is in league. Other heroes have blinks too but im just going to focus on the item itself. Do you think that Flash could be balanced if it disjointed auto attacks and point-click abilities? Disjointed meaning the projectiles would miss their target if they flash before it hits them. How many times have you died because you flash but die anyways because there's an autoattack already in the air but hasnt hit you yet? I feel like flash would still be balanced if they added this to league because its on a 5 minute cooldown. What do you think?
