I don't know how effective the shake to recharge flashlight idea would be. The ones I have seen you have to shake pretty violently to get the plunger inside moving. Unless you wipe out alot, I don't know if this would work.
I think a charging circuit would be impractical on a skate board. Your options are pretty limited. You could use a solar panel if you like to do alot of skateboarding at noon in the desert and can manage not to step on the panel. You could spin a small generator off one of the wheels if you don't mind a bunch of extra crap hanging off the bottom of your board.
Just about any battery is going to run a few LEDs like you are talking about for several hours minimum. It would be much simpler just to recharge the batterys with a wall charger in the house.
