I actually played on not just planned it.
I went with Rogue1/Fighter3/Rogue1 as my start to the class. I used Jack of all Trades and Able Learner so I could literally use any skill. When I went into Chameleon I started with just fighter or mage or cleric depending on what I saw as the deficiency. When I reached 5th level I started playing the dual as a Fighter Mage (Gish). I used all kinds of buffs and wraithstrike (don't tell me it is broken I know it is but it sure was fun)
I think it may be interesting to go Duskblade 5/Chameleon 10 Very little arcane spell failure, you get to use a shield, and you can transfer spells through your sword.
