Admittedly, this suggestion might be a bit of a stretch and is rooted in fanwank obscurity, but I really wanna suggest it.
The Beast Wars Magnaboss component molds as three members of the Covenant.
Prowl (possibly with a new head) as Leonicus for obvious reasons. His deco could play around with various oranges, browns, golds, and silvers to differentiate it from Prowl's deco.
For the other two, since there are no birds or elephants in the Zodiac from which the Covenant drew inspiration, I had to get a bit... creative.
Silverbolt as Virgol. The robot mode is slender enough to pass for a fembot, and of the visible members of the Covenant, Virgol's design bears the closest resemblance to the basic outline of the Silverbolt mold's robot mode, complete with her "hairdo" even slightly evoking the shape of Silverbolt's "headdress" (if you squint hard enough) formed from his bird head set atop his robot mode head. Her deco would make her a yellow and purple eagle, giving her deco an almost "Universe 2003" quality.
Ironhide as... well, this one was tricky since none of the Covenant bear any resemblance to Ironhide's hulking bruiser-ish shape, but I ultimately went with Libras. Since the angled position of Ironhide's arms and shoulders in robot mode sorta resembles the look of an old-fashioned scale, and because the kibble halves of the elephant head are attached to Ironhide's shoulders in positions similar to the scale plates attached to Libras's own shoulders. His deco would utilize various shades of silver, blue, and purple.
These three would be presented as the last surviving members of the Covenant in a version of "Terminus" in which the others were all killed during Point Omega instead of how things played out in the main version of the story, leaving these three to be the only ones left to enter the Matrix of Conquest and engage Unicron's Dark Essence avatar directly.
Combined together, the resulting Magnaboss redeco would be "Beast Wars Primus", or at least an avatar representing what a Beast Wars version of him would look like.
