The better is the enemy of the good...
..or something like that, right? JIMO died because it was over-designed into Pegasus from Battle Star Galactica.
Europa needs a solid geophysics orbiter before a lander would be prudent, I think. There are still so many knowable unknowns that a dedicated orbiter would help determine. Compare MGS and Pathfinder, two contemporary Mars missions, and MGS wins in terms of data, scope, and lifetime. Plus, it's still going!
Give the orbiter some time, then I guarantee we'll know exactly where we want to attempt a very technically challenging landing on that smallest of Galileans.
