First, *YOINK*
I agree with some of the comments of earlier posters. I like mattdm's skill suggestion. 2 skills from multiclass feats + any 2 skills seems like plenty, and Jack of All Trades is very appropriate.
I also see no need to ignore the prerequisites on multiclass feats. I think you could clarify Power Versatility by stating that your highest-level and second-highest-level power in any category must be from different classes (e.g. if you're a fighter/wizard, and your 1st-level Encounter power is a wizard power, then at 3rd level you must select a fighter Encounter power).
I think this also mitigates some of Exen Trik's concerns. The dabbler is numerically better than a wizard (say) but doesn't have his class features like implement mastery and spellbook and is forced to have a non-wizard power as his second-highest pick in every category. I see the point about a defender/defender hybrid, but those guys already multiclass well using the normal rules (because so many of their powers are melee weapon Strength-based).
Dabbler isn't a very sexy name for a class but I can't think of many good ones either (Adventurer? Hero? Yeoman?).
