Names After an Eternal Bond Between Sun and Moon Miqo'te

[Cabrean]

My character is a male keeper of the moon miqo'te EB'd to a female seeker of the sun miqo'te, both with lore-appropriate names.

That said, we are also a couple irl.

I want to shift my name a bit to reflect this in-game, but I'm not entirely sure what the best way to go about it would be (while breaking as few naming conventions as possible). I've searched through the forums and I failed to really find any kind of lead.

So, I come to you guys for advice.

I've considered two options, the first being to include her tribe's letter at the front of my name to show a kind of integration through EB. The second is to take her "surname" as my own surname. I've also considered just using a fantasia to become a seeker of the sun myself, but I used moon miqo'te naming conventions to include my irl mom's name in my character's forename, so I'd very much like to keep it if possible.

Those of you well-versed in miqo'te lore, what do you think I should do in this situation?
