Hybrid Avenger|Swordmage is also a pretty bad combination. You'd need, at the minimum, 3 stats, Wis and Int as primaries and one of Str or Con as a secondary, which means that your important stats will be low overall, meaning your attack and damage bonuses will be low compared to standard, so you'll hit less often and do less when you do hit. Generally, hybrids should either have both sides share a primary stat, or the primary stat of one side should be the secondary of the other and vice versa.
The sorcerer, however, is a decent idea, though it doesn't really sound like what you want fluffwise. Maybe you should try a pure Avenger, pure Swordmage, or pure Monk?
