Concentrating on an ongoing spell (as in one with Duration: Concentration) doesn't require a Concentration check. It requires a standard action, which is an entirely different kettle of fish. You can be made to make a concentration check, if you take damage or the like, but not from casting another spell-- that doesn't work because of the actions involved.
The only way to outright avoid concentration checks (from Casting Defensively, etc.) is with a mythic path ability. To my knowledge there's no way to bypass the standard action requirement to concentrate on an existing spell.
EDIT: Also, Duration: Concentration outright specifies that "You can't cast a spell while concentrating on another one."
So yeah, unless there's something to break that rule which I'm not aware of (possible, certainly), then there's no way to do this.

Well, if you want to be a Gnome and cast Illusion magic, there are these:
Effortless Trickery
Phantasmal Gem
You may be able to get the Gem without being a Gnome, but it's not worth as much if you aren't able to recharge it.
EDIT: Bah, I've been ninja'd while I was searching through the spells. xD

It still doesn't get you around the explicit "can't cast another spell" problem.
And it shouldn't.
Pretty much every spell out there that requires concentration to maintain has some pretty strong effects. It's kind of like casting a new spell every round and getting the full benefits, but without actually casting a new spell - you concentrate to maintain the old one and still get the full benefits.
That's kinda big.
Letting you do that AND cast more spells is like letting you do two useful things in a round (or three if you also do a quickened spell, too).
Casters are definitely powerful enough that they don't need that.
I don't know of any ability that makes this work and I'm sure I'd ban it very quickly if I came a cross one, except maybe at the extreme upper levels/mythic tiers where characters are nearly godlike anyway.
