Good idea!

I can understand the allure but I find the font very hard to read. Also the runes are exotic but strange next to 'Kitchen' spelled real plain. If its a thief's map perhaps the glyphs would be from traps or treasure chests?

Perhaps the map was done from rough notes in the field and then a master made when there was more time. Each room might have its own map with detailed info and the big map might have the typical position of guards etc...
