I was thinking of this awhile back, Medicom has the molds & they seem to reuse them when it comes to carded figures, just a difference in the figures ala Sandtrooper, Luke, R2, Fett except the first carded Fett where they just used the chase figure.
Putting a Vinyl Jawa on a card would be a ultimate nod to the vinty line. Not sure if they would change anything to the figure, its fine where it is but do to the rarity on the vintage Vinyl Jawa, its possible seeing him carded like the 12 back. They could even put on the proper vinty bubble to give it that look.
Dunno, just a hunch.
Makes sense, just curious I was.
