I would definately be interested, but I see a couple of things things you would need to sort out first before you could start on a venture like this.
Firstly voltage conversion. You would need to build some kind of relationship with the manufacturers of the kit you import so that they would be prepared to supply you with the relevent bits. I wonder how easy this would be as you would probably be seen as undermining their distributors. You would also need to find a decent guy who can do all of the conversion work (not that hard really).
What about warranties? You would probably need to provide some kind of warranty, and what happens if repairs are required? How willing would the manufacturers be to send parts etc?
Finally, I see it as being very difficult to avoid the political backbiting and dirty tricks that the unhappy distributors would be likely to play - you are going to make a hell of a lot of enemies!
IMO, if you could address and overcome the above issues then it would be a much needed breath of fresh air, and I think you would find many punters willing to support such an ideal.
Just a few thoughts.
