You could buy a dynamo hub and replace the hub on your wheel with it. I did it (on 2 bikes) a few years ago and rebuilding the wheel wasn't that difficult - getting started being the hardest part (I made a jig to hold the hub and rim in the right place relative to each other).
I built a dynohub wheel earlier this month, just laying it on a table according to the Park Tool website instructions. My first wheel build and seems to be satisfactory so far. I did subsequently use old forks and a dial gauge to true it to about +/- 0.3 mm from probably twice that.
However the OP specifically mentioned the hub as a good part of the wheel. There is probably no solution to that, you either bite the bullet and rebuild the wheel with new spokes, or build a new wheel, or use a bottle dynamo, or battery lamps.
The reason for my build was that after forty years of bottle dynamos, during which I thought I had encountered every possible problem, and the solutions, and seemed currently to have a nicely running bottle dynamo, an entirely new problem appeared:
Which was just too much.
Now I am ready for practical study of the problems of hub dynamos. The one that comes to mind is regreasing the bearings, which presumably needs doing just as often as any other hub, but is now part of a complicated electrical component that is not, perhaps, meant to be user serviceable.
