I'd worry that not just the jumper pins can be shorted, and whether what 
was really needed was a proper enclosure.  If not, then what I'd do is 
probably to go to my favorite vendor for RasPi/Arduino junk (AdaFruit, 
perhaps).  I'd buy an assortment of shrouds, of the sort they use to 
build their cables (which fit over header pins like these) -- the 
assortment is by far the cheapest way I know to obtain them.  Then I'd 
buy the crimp pins that go inside, and insert them without wires.  If I 
was super paranoid, I'd use my flush cutters to trim off a bit of the 
area meant to crimp the insulation, so that no metal was near the top 
when I put my connector on the header.

You can also use the housings to neatly build up your most used jumper 
configurations for quick changes.
