Overbooked Home Game - Suggestions?

[Snowslide]

I did a search, but didn't find anything.
I have room at my table for 10 players, and am having a game tonight. A couple people coming want to bring a friend or brother who is up from out of town, and I would like to accomodate them. Here is a copy & paste of the game we will be playing tonight:
===========================
We have been playing the following:
No Limit Texas Hold'em Tournement
$5 gets you $500 in chips ($T500)
Unlimited re-buys for 90 minutes.
Blinds increase every 15-20 minutes (Depends on # of players)
You can add-on $5 to start the game ($T1000 for $10), and add-on $T500
at the end of the re-buy period)
We have been modifying the prize pool lately.
2 paid places 80%/20% (Less then 10 players)
3 paid places 60%/30%/10% (10 players)
==============================

So, it looks like we will have about 12-15 players tonight.
This what I am thinking, instead of having one big game, have 3 games going at once, one end of the poker table, the other end of the poker table, and a game at my kitchen table (about 5 feet away from my poker table), and randomly seat players, using a deck of cards. But every 30-45 minutes, reseat everyone randomly again, until we get down to 10 players, then move everyone to the poker table.
What do you people think of this setup?
Any suggestions?
Thanks,
