I don't think it is. This is from the Wikipedia page about the Infinity Gems
"Following the cancellation of the Infinity Watch series, in the one-shot title Rune/Silver Surfer the Gems are stolen by the extradimensional vampire Rune and dispersed throughout the alternate universe Ultraverse. The Asgardian god Loki enters the Ultraverse and collects the Gems, also discovering the existence of a seventh Gem - Ego. The character learns the Infinity Gems were originally part of a gestalt being known as Nemesis. The Ego Gem, possessing the Avenger Sersi, merges with the other Gems to reform Nemesis and battles superhero teams the Avengers and Ultraforce, before being dissipitated once again."
This takes place in the Black September storyline, as far as I can tell:
Rune/Silver Surfer
Ultraforce 8
Ultraforce 9
Ultraforce 10
Ultraforce/Avengers Prelude
Ultraforce/Avengers 1
Avengers/Ultraforce 1
Ultraforce Infinity
While not collected, they should at least be easy to find in $1 bins.
