Intelligent Blademaster means that STR is virtually a throw-away stat for Swordmage, so Eladrin becomes a viable option.
Ok, I am makeing a swordmage...and I am stealing your idea...here is my blog:http://www.enworld.org/forum/blogs/hardcoredanddgirl/1531-i-hate-change-switching-4e.htmlI'm also inclined to recommend swordmage.
At the risk of being shamelessly self-promoting, my 5-part blog series on how and why I built my swordmage might be useful to you. It starts with

Multiclassing into wizard right away might be a good option for you, although I decided not to go down that road.
