As soon as MESSENGER gets to Mercury, the most poorly explored planets in the solar system will be Uranus and Neptune. Could this lead to a revival of interest in the ice giants and their retinue, in the same way that the existence of New Horizons is perhaps partly due to the Pluto stamp*?

I think they should build two spacecraft, and send them both to JS and then one to Uranus and one to Neptune.
Building the spacecraft simultaneously will keep the building and development cost low.

Then the time it takes to get to Uranus and Neptune, if breaking is much a problem, then the speed to get there should be lower, at least much slower than New Horizons gets to Pluto.
