Hey there!

I'm wondering if you'd be interested in any of these:

🌼Avatar the Last Airbender/Legend of Korra (different time periods, we can change that around so that the fandom still existed)
🌼How to Train Your Dragon/Dragon riders stuff
🌼Fullmetal Alchemist/Brotherhood

That's all I've got for now! I'll check back soon to see if there's a reply!
