Not a good idea with ESD sensitive electronics. You could use antistatic foam, though.
Its resistance is high enough that electronics won't notice its presence.
A variation on the connector idea: use an insulation-displacement type connector (the kind
that you mount onto a flat cable assembly) without the cable. Just snap on the cover over
the i-d pins and you have a fully insulated assembly with the pins acting as spring clamps
for the jumper pins.

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.
I don't know if it's applicable, but I use hunks of extruded polystyrene
insulating foam to protect the pins on my wire-wrapped projects.
