Alolan Exeggutor used for catching?

Question

So, I was just looking through Alolan Exeggutor's information, and thought of a set for catching that could be pretty decent. Here is what I think it would look like:

Alolan Exeggutor with the Harvest ability, holding a leppa berry
-Synthesis
-Dragon Hammer (decent power, STAB, no side-effects and good for most Pokemon type-wise)
-Sleep Powder
-Sunny Day

Would this be a good catching moveset, for shiny hunting by SOS especially, or is there a better moveset?

Comments

The ideal catcher should also know false swipe. Conventional stuff like Parasect, Smeargle, Breloom, and Gallade are still better.

Well, I understand that. Just thinking that an odd hunter might actually be useful in some scenarios. Plus, this Pokemon can quickly heal and get it's PP back. Well, in sunny weather. That may influence the moveset...

I don't want to post an answer that just says "no", but sumwun is correct, it's never a good idea to go shiny hunting or just pokemon hunting in general without False Swipe.

My point is I want to try a different method of a hunter. Sure, this may not be able to properly get them on low health, but it is an alternative that could have a possibility. The point of this one was because most hunters typically have false swipe, healing move / pp move, high damage move and a move to sleep/paralyse. I want to try something that can survive on its own to get through them without having to rely on tons of berries. This Exeggutor can shiny hunt for you even if you have just one Leppa berry and a way to easily get the other Pokemon on low health. Besides, the effects (sleep) will help with catching more than low health.

Aaaand you just answered your own question.

Actually, lowering HP multiplies the catch chance by 3, while sleep multiplies the catch chance by 2. If you had to choose between false swipe and sleep-inducing moves, false swipe would be better.

The asker already knows most of the answer, so I'm answering here mostly to take it off the unanswered list.

The only problem I have with this is that lowering a wild Pokemon's HP multiplies its catch chance by 3, while putting it to sleep only multiplies that chance by 2. If you had to choose between false swipe and inducing sleep, false swipe would still be better.
