Yes and no honestly.

It's interesting because for the Neomorph although the Pods act like Eggs, the Motes act as the Facehugger, they actually disappear into the host (although they may also die inside after serving their function) as depositing the mutagen.
In this way the Trilobite's closer to a Facehugger functionally using a human being's ovum with sperm as the Egg.
But it makes me wonder if Plagiarus Preapotens, and the Plagiarus Linesteres, exist basically as forms of The Pathogen itself programmed to perform a specific purpose.
Meaning that the Motes probably deposit "Plagiarus X" let's say.
And that the Trilobites probably deposit "Plagiarus O" for example.
In the way this applies to the main Alien species with the three types of Egg and Facehugger we now know of.
The Pathogen causes death, either by cellular breakdown, or by creating a hybrid form, that always develop identifiably similar features.

QuoteThe Pathogen's internally consistent with obvious rules, within the films themselves, mainly Alien Covenant though I believe.
It does not result in the biomechanical for a start in fact the opposite. But with other things present recognisable in the titular Alien. Simplest organisms logically appear to change the fastest like Demodex folliculorum or Demodex brevis most often visible in the eye or worms becoming Hammerpedes.
As stated it's designed to clean a planet of all non-botanical life. To achieve this it ultimately either kills you outright or creates a hybrid form, the former we see with the Engineers on Planet 4 and with the Engineers on LV-223, the other we see with what happened to Doctor Charlie Holloway and Sean Fifield and the exploding head. (Becoming unstable hybrid forms themselves with high aggression, bulbous, bloated, with further distending arms and legs, pale skin and a overall virulent infected appearance- hence Prometheus the film mentioning Ebola in the story multiple times for a real life comparison) And afterwards it spawns Neomorphs from Motes and Pods. (hybrid forms) I do not think it's as complex as appearances suggest.
"The Deacon" (In essence a Neomorph itself in all but origin) only exists because by David's own admission the Pathogen reacts to human sexual organs in an alternate way, hence he uses Doctor Elizabeth Shaw's to fashion the Alien, and bring an equally worthy artificial intelligence in his eyes into existence.
Because in terms of function it's all in essence identical:
A Pathogen infected sperm and ovum/Pod/Egg
Trilobite/Mote/Facehugger
Deacon/Neomorph/Alien
So you can say although not identical in appearance they do come from the one family tree if you like, and a Deacon's still closer to it's Neomorph kin than a Plagiarus Linesteres Praetomorph, and far from a traditional Plagiarus Preapotens Alien.
