Xiangli Yao with moongazer sigil plus Yinlin and Jianxin?

Hello everybody, I'm not always the best at theory crafting so I just come to the people that know more.

I pulled on Iuno's weapon banner and got a double of moongazer sigil in a single 10 pull!

I've always wanted to build xiangli yao but didn't have his signature. I want to know two things,

1. How well does moongazer sigil work on xiangli yao? Specifically how good is it over abyssal surge?

2. Is the team comp in the title viable? I have a fully built Yinlin from my time playing with Calcharo, and my thought is jianxin can apply the shield to proc moongazer sigil, but I'm not sure if this is a realistic team rotation or not? I could always slot verina or shorekeeper in instead, but if I can keep them free for other teams and this team still work that would be awesome. I honestly care more about the team being fun than it being optimal, but it still needs to clear or it's not fun haha.

This community's been so awesome in the past I appreciate the help!
