Here's your answer:
Spoiler:You have to go through a long cutscene before choosing your starter (not sure exactly how long, but it's approximately 3 minutes) so unfortunately Alola starter soft-resetting will be annoying. It's also why I'll just stick with a male Popplio if it's what I end up with.
87.3% chance of getting male = approximately 9/10 times getting male
9 x 3 = 27 minutes
Lets assume really bad luck:
18 x 3 = 56 minutes
Tbh, if you really want a female Popplio, 1 hour is probably worth the investment because you will likely play the game for many, many hours. But for a shiny, definitely not worth it.
That would sadly take A lot of resets and would take a ton of patience and luck since the chance of getting a shiny starter is just like finding a shiny pokemon in the wild But more difficult as you have to reset the game multiple times just to get a chance of getting one.

Powersaves are your friend.
They're really not. It destroys the purpose of playing a video game in the first place. That's literally slapping the creator of the game in their face. Although, Game Freak loves getting slap in the face making my opinion Type:Null.
Why do they destroy the game? If people want to use them, they're entitled to. Not everyone has enough spare time to spend hours and hours on end (potentially even days) soft resetting to get a shiny starter.
Because your not suppose to get a Shiny Pokémon at the beginning of the game in the first place? Why is this even a question? o_o
Plus, who does that in their first play through? What's next? Your gonna give your starter Perfect IV's and at the start? I do understand the OP color preference, but that's not how you should earn your Shiny Pokémon. Which leads me to another question! Is there a new breeding mechanic in Pokémon Sun and Moon or is it the same old RNG based mechanic?
Quite a lot of people do that in their first play through actually because they much prefer the colour as the OP said. What has perfect IV's got to do with having a shiny? A shiny is purely visual and has no affect on how strong it is. And I'd imagine the breeding is the same, except without bikes, but I'm not 100% sure.
