Sure, you could do Sorceror 1, Wizard x, (insert other class to make up to 5 here), DD the rest... would be fairly pointless tho.
Level 0: Detect Magic, Light, Message, Read Magic
Level 1: Shield, True Strike
I'm not sure Shield is particularly useful. It will only last 1 minute due to your caster level, and you can only really utilise it before a fight if you don't want to cut into your damage dealing time. True Strike is better (no asf!) but again fairly limited use considering that alot of the time you'll be better off simply attacking twice (or more with full attacks) rather than casting for 1 round, then attacking.
Thats why I favour bard 4/barb 1/DD x... I go with the mithril chain shirt. Its alot less armour, granted, but it doesn't reduce your movement, no ACP, only 10% ASF, and you get 2nd level bard spells. And there's alot of useful bard spells. Cure Light/Moderate Wounds, Heroism (altho that overlaps with your bard song), Glitterdust, Feather Fall, etc.
You'd be losing a bit of combat oomph, but you pick up a bit of utility (esp with the extra skill points).
