A ground set using that style would also work. Hopefully, they will be easier to obtain than the current ground sets. I don't include the Jem'Hadar ground set with the others since the only thing that looks different is the weapon.
It seems like they already have the parts for a "Devidian Set": The Sheild, the Ghostbuster Gun. If they just re-purpose an armor and use the Ophidian Cane, they could have the first 4-piece Ground Armor set.
