Decep deaths: Yes, but no if...?

Should it be appropriate for us to assume that specific Decepticons will be protected from death in Dotm, by the Dotm writers (or Hasbro) on the grounds that they have died in other TF realities to produce new characters? That is, would Hasbro keep a character who eventually yields a Herald of Unicron/other notable in reserve, or just import the herald/other later on a standalone explanation and reason for existence?
eg:
Starscream:Ghost of Starscream, (maybe Sunstorm(?))
Megz: Galvatron
(Scourge,General Thrust,Cyclonus,Goldbug,Armada Wheeljack,Battle Ravage)etc.
This would imply that some of the existing villains are interchangeable upon death with new villains, but also new factions.
Galvatron is perhaps the immediate contender for being imported without killing off Megz.
Such an action could cause us, as fans, but also a receptive audience, to Assume events will go one way but surprise us with another direction. (eg seeing Galvatron immediately implies Unicron, but can imply interdimensional war instead).
