Doubling your inputs on interface?

Is there some kind of xlr cable that can split into female ends so you can have a Left/Right stereo micing running into one XLR input to save space? And if you want to cheat, can you split up that "stereo" track into two monos?
 
XLR is a mono wire and a shielding wire, right? What's to stop you from sending a signal through the latter to get a second channel?
 
XLR is two cores and a shield.

The two cores carry a positive and negative of the same signal. Any noise picked up shows as a + or minus on both cores, so when one is inverted (to make the signals the same) the noise cancels out.

You can't send a signal down the shield cable; That's no good.

It's common to all inputs and connected to the chassis of the interface. That's connected to ground so your signal would go straight to ground.

If there was going to be a conceivable way of doing it it would be to use the + for one signal and the - for another, but even then the preamps circuitry is gonna be balanced and it would involve a shitload of DIY, and your inputs would now be unbalanced.

I don't even know if that's possible, but if it is you'd be so balls deep that you may as well just built an interface with more channels.
 
Another thing: If your interface only has 4 inputs, that means it only has 4 converters. No matter how many things you plug into the front of it, it will still only be able to digitize 4 mono signals.
