Spider phobia and jorogumo? (No spoilers splease!)

[Quentin Coldwater]

Hello, I'm playing in a Season of Ghosts campaign (currently level 6), and I'm about to run it as well for a different group. However, someone in that group has a heavy spider phobia (the legs are a big trigger) and prefers not to encounter them. Even saying the word is taboo. Which I totally respect, of course. But upon reading up on the campaign and on Tian Xia in general, I suspect the jorogumo are going to become an important theme in the campaign. Due to spoilers for myself, I don't want to know if they are or not (though I have a suspicion they will). I have a simple question: how important is it that Ugly Cute is a spider as well?

I've already censored the player's guide for that player, and I'm planning to replace any spider creature with centipedes or something similar. Ugly Cute is going to be a stone toad, and I'm thinking that if I encounter any jorogumo, I'll replace them with mantis-hybrids, instead of spider-hybrids, so I should be good. But like I said before, if Ugly Cute is going to become plot relevant, I'd like it to stay consistent. I can retrofit Ugly Cute into a mantis as well, or make the jorogumo toad-people (I'd prefer the former), so either way, I'm fine.

Thanks in advance.

EDIT: Also, are there any other spider-related adjustments I should make, and keep consistent?

Since you say you are also playing this AP, I will take it that you are aware of the big twist in book 3? If you are not, then stop reading this AP at once, books 1 and 2 will spoil it to the GM even if it isn't revealed to the players yet. You'll spoil it for yourself! (And the twist is very much worth it!)

Jorogumo will feature in an unexpected way later, and Ugly Cute being a spider will matter in a small way that relates to Jorogumo.

If you make Ugly Cute and Jorogumo both into toads or both into mantii, then that part is preserved, its cool.

I've just had one big twist in the middle of book 2:

Spoiler:

We're in a time loop/mindscape.

From cultural osmosis, I think I've also been spoiled on the thing you're hinting at:

Spoiler:

The players are the titular ghosts?

So I guess I've been mostly spoiled, but I'd like to keep it as spoiler-free as possible.
