Detect Abyss Idols?

Is there a way to make abyss idols a quest so you can see them when you go into an abyss?
I unloaded the client with RABCdasm and edited dat27 or whatever, and changed abyss idol to quest..
Is there other things needed to be done? Or is it just not possible...?

not possible, the map is server-sided

If this could be done, you could also make Candy Gnomes, Kage Kami's, and Trooms in other dungeons quests as well...

This would be really awesome if possible, I don't see why it wouldn't be.

Hoping someone who knows more posts to verify this.

Sorry to burst the bubble, but it's going to take someone extremely creative to figure out how to reliably solve this problem. Problems? a) the dungeon isn't completely loaded to your client when you enter it, and b) the server doesn't send any info about the mobs on the map unless they fall within a 20 tile radius of your character. The quest mob info is sent to your client, no matter how far, but you can't set a new quest mob to a mob your client doesn't know about.
