Again, I'm likely late to the game on this as it appears to be everywhere now...
Connor Flynn has built a LEGO Star Wars foosball table to wage intergalactic 'foos' in a living room near you.
The table is 100% LEGO sourced from a variety of parts.
Here the set-up appears to show rebels versus stormtroopers, but I could easily see minifigures changed out. Jedi vs. Sith? Separatists vs. Republic?
In fact, I bet if some enterprising person could get it the price point right, you could sell a variant of the table (likely not made of 100% LEGOs) to put any minifigures in. Hmm...
