I've been practicing it in the lab today and I can do Parry-hop to downsmash/upsmash pretty easy (around 4 time in a row on average with a high of around 9 or 10 in a row). If you hold down the whole time you can use A and make it d-tilt as well. F-tilt is kinda tough though lol.
It's really all about finding which buttons work best for you to make it consistent. I can do parry wavedashes pretty easy too now which is kinda important against falco. The hardest part of parrying lasers is making sure you are using as many invincibility frames as you can. The more you use the more leeway you have to shield earlier so you don't get hit by the lasers as often.
When doing Parry-hop to ground attacks I tried a lot of configs to see what see if anything made it significantly easier... there isn't a button combo that makes it free without practice, but it's not bad with practice. Right now I'm using R for shield, then double tap Y and hit the c-stick/A etc. The big tip is learning where to concentrate during the move. Like, if you start missing them, just try shield then jump, because that's super easy. Do that once or twice to get your rhythm back and then concentrate on releasing the shield before the 2nd Y tap. That's the only hard part really, is keeping your fingers fast on the shield release so that you don't pop shield after the quickhop. It's not hard after practice but it takes some getting used to. I think that doing rapid Parry-hops should be easier than doing Parry-hop attacks since as long as you release R before the landing frame and freshly depress it, you will be able to jump out of shield when you press Y. I think your hands have more leeway with continually parrying vs using one parry into an attack.
Also, remember after you depress shield and you have 5 frames to jump out, L/R must be fully depressed to be able to jump out of shield, so just smack the button in hard and fast. If you didn't fully depress it, you'll see your shield pop even if you timed the jump right.
