I think it makes sense from an aesthetic and lore standpoint though, it's got spikes all over the body like the potential for argument's sake host, and like the Alien spawned of animals from our world it can spit acid and unlike the ones spawned from sapience primarily moves on all fours.
Considering the Vootervert Alien's essentially described as a Alien that only took on the useful traits of the host animal from Phalanx I think this tracks.
And with the way The RPG's repurposed the Royal Jelly, and thus the Charger and Praetorian, I think it works in nicely.
