To the general public, they probably wouldn't sell well, unless they sold them in 3-packs similar to the Unicron Trilogy at low prices. That being said, releasing characters like micromasters would help sell them to fans wanting Classics Micromasters, even if they are in the form of a Targetmaster.
Blazemaster has a proud place in my Classics collection as Classics Blazemaster and I would love to have more characters like that in 3 packs or as bonuses to larger figures (such as Generations legends and deluxes) to fill up micromaster collections.
I liked minicons (the Cybertron ones anyway) when I was a young child and the characters didn't really matter to me. They have both a robot and vehicle mode, as well as a gun mode. That would sell pretty well to your random child who's not too picky about characters.
