Is anyone aware of a USB OTG cable that will allow devices to be plugged into the shield while also allowing the device to charge?

I have a OTG USB -> USB Hub -> USB Ethernet + Keyboard + Mouse + Controllers plugged in so that I can use the Shield as a console for my PC games on my TV @1080P/60.

Everything works perfect, but when you take up the micro USB slot with the OTG cable, you are running off battery with no way to keep the device charged. I get a reasonable amount of charge time (on a full charge I have never blown out the whole battery life while gaming), but it's a pain to swap the cable between charge and OTG when it does need some juice.

I've seen a gentleman by the name of Timur who came up with a custom kernel for the Nexus 7 that allows such functionality on that device.

Is there any solutions like this for the Shield, or is there any cables that will accomplish this without modification?

Something like this plugged into the hub, then into the charger?

My investi-googling tells me that it won't work. It powers the USB device, but not the host.
