A repeater might be feasible, but it would introduce additional lag. Maybe not what you want to see in a gaming video display, but it might be the additional lag is so tiny it doesn't matter. Say an additional 10ms for example - just to pull a number out of thin air - would never be noticed by any human being who's ever existed.
As for much greater range, high-bandwidth wireless tech has a propensity to not penetrate very far through solid objects such as floors and walls (higher bandwidths usually occupying higher frequency radio spectrum, which has inherently shorter range inside a house at least), so I don't think we'll see an "anywhere in the house" repeater.
Also, if you live in an apartment such a device could certainly cause interference with your neighbors' wuu gaming by the way, so I doubt it'll ever see the light of day even if any/all technical difficulties could be solved.
3rd party pad? Never, unless Nintendo officially sanctions it. They're liable to send packs of vicious attack lawyers at anyone trying to copy their wireless tech, device design and whatnot.
