I'm bad at expressing my findings theres nothing really to explain, this is all my imagination and thoughts that came to me while I was at work so this might be way off track as well. Now I don't know if anyone ever brought this up/posted this before so feel free to call me stupid for not researching this a little bit more.

I've seen everyone do all these calculations and trying to overlap the wishes try to find the blanks and what not. What if the blanks were in plain sight? Something that everyone would overlook? Something so simple that you might think it's nothing?

(Images I'm providing are from google since I'm at work at the time I'm posting this so some of them have shitty resolution)

I saw this while I was going through my collections tab - "Destinations: Last wish" - What grabbed my attention was the logo, the black dots on the logo to be precise https://i.imgur.com/ClAUM0L.png < picture of the image.

I looked at the blank wish wall and you could fit these dots in the wish wall perfectly https://i.imgur.com/JKoWYnr.jpg < marked the black dots from the logo on the wish wall.

Now the problem is the picture above could be where the actual symbols are OR they could be the blanks, so I went ahead and made this picture https://i.imgur.com/GYBYc6n.jpg

After reading some lore on the armor for the Last wish raid I came across one specific one, the Titan mark. It reads: "Mara stared at the wall of wishes. She had no more bargains to make. Her plans were in motion.

There was nothing left but the wait.

She pulled a sidearm from a hidden holster and cracked a dozen rounds into the Wall."

Now I'm pretty sure I've seen people talk about this specific part of the lore somewhere and the reason why I mentioned it was because I'm leaning heavy to the possibility that the second picture with the 12 symbols might be the actual combination.

All of this information is just random stuff that popped up in my head so it might be completely wrong and or already been discovered by someone else so yeah.

Tl;dr : possible wish 15 blanks could be linked to the black dots on the Logo on the "Destinations: Last wish" on the collection tab.

Edit: Changed a link that was wrong
