No, it isn't lame in the sense of truly being something that isn't worth looking at, but from a toy manufacturer's perspective it wouldn't make sense to make, the cost of the mold, cost of the design, cost of the paint , cost of the packaging, the cost of distribution, and the cost of promotion...
You make the comparison to Unicron, yes the Unicron toy is to total piece of crap, but you can't make the comparison because hundreds of thousands of people know what Unicron is, and many want one... For Christ sake, the thing was played by the voice of Orson Wells!!! That alone makes it a pop icon... The VF boosterpack on the other hand... No one would know what it is, no one would be able to justify the cost, but most importantly stores wouldn't carry it because they would rather take up their valuable shelf space with toys that they can sell a ton of, like that POS, Unicron.
