If the DM can handle an "unbalanced" group, it's not a problem.
In our current group, the DM used a rather odd method for character creation. We each rolled one sets of stats for ourselves. If the set didn't contain an 18, roll again. And keep rolling, until you have a stat set with an 18. Now, pick any one of your sets to use.
I had to pass on my set with the 18, because the other scores were total crap. But the set I finally settled on was rather odd. I now have a STR = 5 and CHA = 7 for my gnomish rogue. Whereas, most of the other party members seem to have 12+ in most stats, with an 18.
How do I compesate? I play a rogue. I don't do front line fighter stuff, unless I can flank for the sneak attack damage. I stand in the back, and hurl items out of my bag of tricks. I use a crossbow. I took
Weapon Finesse: Dagger for a feat in case I have to get in melee (that makes a huge difference when your STR = 5 and your DEX = 16

).
The DM placed a set of magical lock picks in one dungeon. They add +3 (instead of the usual +2 for masterwork lock picks). But they also allow my rogue to take damage to make up the difference on certain Open Lock skill checks. With a CON = 14 and near max h.p., he's a tough little bugger who can take a little extra damage to help the party get past that lock....
So, as long as you're comfortable with an "unbalanced" party, it doesn't have to be a problem. Just give each character a place to shine occasionally, stress team work, and have fun.
