It's hard to tell without ever having played the game, but based on what I've heard from "E for All" and Gimpyfish's character analyses I'm inclined to say yes.
From what I remember of Gimpy's impressions, Meta Knight is already very good on his own. He's fast with great recovery and can combo and rack up damage very well, although he lacks any decent killing moves. Ike, on the other hand, is almost the complete opposite. He's very slow and has horrible recovery, but almost all of his moves are killing moves. He didn't at all fair well in one-on-one matches because of this, but in free-for-alls he faired very, very well, to the point where he was almost dominant. If I were to guess I'd say that he'd also fair well in team battles, so I wouldn't at all say we have any problems individually, in fact individually the team's very strong.
Aside from it's individual strength, the power/speed pairing of the team would porbably also greatly benefit it. Each character covers the other's weakness(es). By this I mean Ike's speed (or lack thereof) and inability to combo is in turn covered by Meta Knight's speed and ability to combo. Meta Knight's lack of decent killing moves is made up for by Ike's variety of killing moves and ability to kill at low percentages.
In theory, I'd say (so far) that this is the best pairing you could have for a team battle.
