Unique Map Ideas

WG introduced a series of new maps with the last round of recon testing and Outpost just went into the game. In one of the posts about the design of Outpost, WG explicitly stated that they will not make maps with many different alleys or angles because of "lack of a frontline". This thought process is what gives us the same copy/pasted 3 corridor dumpsters that makes games repetitive and unfun. You drive your tank to one of half a dozen positions and sit there. If you win, you push up and stop at the humungous killzone before the enemy base, and continue waiting.

While it is possible for WG to make some interesting maps that actually have areas to attempt different maneuvers like Klostertal while balancing the boring corridor stuff, there's an idea I had for a corridor map that would align with a recent trend in some WG maps.
In recent years, WG has definitely been experimenting with "indoor" areas like the cargo tunnel in Safe Haven or the numerous passages in Kraftwerk. It should be evident that tanks are not necessarily designed for indoor use, but it got me thinking of a place where you could fit a tank inside an enclosed space.

A mine/quarry.
WG could make an entirely enclosed map and fulfill that need of a space where tanks can function while "inside". Literal corridor shooter, extremely limited options of where to go, and perfect for tanks with terrible depression.

There'd definitely need to be some kinks worked out (lighting and sound design in particular), but I personally think that a map set inside of a mine would be kickass. Even if it wasn't inside the random queue, it'd still be a refreshing way to add a different area to something like Mirny-13 or potentially part of a desert FL map.
It'd be a novel idea for the game and would need vigorous testing, but could be a lot of fun if implemented.

Anyone else thought of map ideas they'd want to see in the game?
