First thing that I can think of for glukkons would be Al the Vykker's
Campain Tour though it's very unfinished if I recall correctly.
As for scrabs and paramites, the only thing that springs to mind is Seargent Big's Exalmex which was about a genetic crossbreed consisting largely of scrab and paramite.
I would suggest looking through Ajiellyn's
Fanfiction Library for stories with hopeful titles. Maybe other people might have more ideas...
(Also, I might merge this thread with the fanfiction library in a few days, so if it vanishes suddenly you'll know where to look.)
