Big Trouble in Little Narnia

On my way home from work and idea struck me. It hit me so fast and so hard that I had mental whiplash for a bit. I realized right away what I needed to do with this idea. I needed to share it. So here it is. What would a mashup of The Chronicles of Narnia, Big Trouble in Little China, and Doctor Who look like? I know, right?! I will give you a moment to collect yourself after I just asploded your brain meats. You better? Good. Lets break this down.

Uncle Chu: China is here Mr. Burton. The Chang Sing, The Wing Kong, they've been fighting for centuries.
Jack Burton: What the hell does that mean? huh? China is here, I don't even know what the hell that means, all I know is this "Lo Pan" character comes out of thin air in the middle of a goddamn alley while his buddies are flying around on wires cutting everybody to shreds, and he just stands there waiting for me to drive my truck straight through him, with light coming out of his mouth!

“Why, if we can get back to our own world by jumping into this pool, mightn’t we get somewhere else by jumping into one of the others? Supposing there was a world at the bottom of every pool.”
~C.S. Lewis, The Magician"s Nephew

There is the basic idea. The idea is this, whoever built the world of the pools still exists(these would be our Galfreyan Time Lords...sort of). They have since moved beyond using something so primitive as the pools, directly. Instead they harness the power of the pools to control the reality flux. Their civilization is powered by the eternal creation and destruction of worlds at the other end of the pools. Then comes the Exile with his Dimensional Bathysphere. He travels the pools with his dimensional companions, often humans from the Earth Ream. 

The People of Charn, desperate to prolong their dying world have begun to bleed the pools together. The Charn will be like the Daleks a bit. Also this is where the Big Trouble in Little China stuff comes in. The Charn begin their conquest of a new dimension through the subtle stuff, bring entropy and chaos to a world and then gradually the dimensions meld. When Jack Burton enters the scene, the invasion had been held off a thousand years ago by the first sovereign emperor, and no Lo Pan, the Charn conqueror is seeking to restart the invasion. All that stands in his way is a green eyed girl, a tour bus driver, a resteraunt owner, and Jack Burton.

So that is the idea I had. I would love to play more in this head space. I think that I would like to use Timeworks, or something like it to represent the dimensional travel. Though I am a bit at a loss how to do it.
