[Generally_Suspicious]

Random idea I had.
Find some one who enjoys making maps.
Have them slap together some random limited time maps.
Like holidays
New releases

Pop Culture Milstones

Slap em up for a week to spice things up (once every couple of months or if anything BIG happens)
N' who knows maybe everyone loves the map, it gets refined, and added to the roster.

Now I don't suggest dev team because of course, their hands are always god damn full.
But if anyone stepped up like "That sounds like a great hobby i'd do!" 
Would it be an unreasonable, non-frequent, event to pull off?
