Depends on how much you like it / how much of a masochist you are.

My assumptions: the wheels are nothing special to begin with.

What I would do:

a. Repack and ride

b. Find a replacement set of cones from the parts bin, toss 'em on, repack, and ride.

In all probability, if you're anal enough to pull apart fully functioning hubs on a mid-range bike, then you'll repack often enough that these mediocre wheels will outlast you. I've never been convinced that it's worth matching cones to hubs unless you actually care a whole lot about the hubs. Which would not be reasonable on this pair of hubs.

Worst case scenario: 20 years from now, when the hubs get bad enough that you decide to get drastic, you will have saved up enough for a nice Trek 520 or the 20-years-from-now equivalent.
