I am actually investigating a similar thing myself. Though, probably for a different reason that the original poster.
Higher power cigarette scale device?

I found there were some commercial e-cigs that perhaps meet your own needs for a higher power e-cig. I suspect that an improvement on anything commercially available would simply be a charging stand that you set your e-cig onto, and it would charge. It may even be viable to make some sort of base with the juice in it that would automatically re-fill the e-cigs juice.
The re-juicer is idea I just had. It is the inventor in me that wants to constantly come up with ideas like this. So, let me think it out a bit more. Perhaps the e-cig could be the same form factor as the traditional old-style e-cig. But, omit the plastic cap on the end. Then, the base has a reservoir of liquid juice, with a wick in it. The user sets his e-cig down so that that wick comes in contact with the internal batting in the cartomizer. It will hopefully absorb the juice as much as it can hold, and not overfill.
Note that I am unlikely to ever pursue this idea myself, but I may be able to offer more details to someone else, if they are interested in pursuing it. Here is a drawing of what I was thinking.
