Your $5 DC bet and the $30 lay (Did you mean $30 odds
behind the 6? Since your DC bet traveled to the 6, you can place a free odds bet and not pay the commission that a lay bet carries.) are still active, even though the table is coming out. If you decide to switch to the "right side" at this point, you can indeed place a wager on the pass line. The best scenario here is if the shooter throws a "winner" 7. That way, you win both your pass bet and your DC + odds (or lay).
If a 6 is thrown, you will lose all the money behind the 6, and your pass line bet now needs a repeat of the 6 to win. If any non-6 point is thrown, both bets are alive (you can make a odds bet on the point if you desire). Now at this point, you are both on the "right" side & "wrong" side simultaneously.
Remember, you can take down any dark side action at any time. So if you like, you can have the dealer return all your action behind the 6*, if it bothers you to have action on both sides at the same time.
* -- It is not recommended -- especially around here :) -- to take down your Don't Come/DC bets, since once a point is established (or your DC bet travels), you are favored to win that bet.
