Quite a bit to unpack there.

-MGMA isn't even in the Sol system anymore.
-I may have toyed with extra-terrestrial developments catapulting genetics and technology, but tended to aim for "[url=http://www.projectrho.com/public_html/rocket/alientech.php]Apes or Angels[/url]"** approach to that, rather than a starfleet federation.
-The monster-girls being the resault of the last acts of man and their machinations upon contact with whatever new biomass they encountered (usually in the "apes" catagory of development)

**Either primitive beasts or extinct hyperadvanced civilizations leaving nothing but archialogical wrecks wraught with eldritch horrors of technology.

So the ship is an ecclectic combination in some places of highly advanced alien wrecks carefully grafted over the old station, [i]and tightly gaurded against tampering, SCP-style.[/i] Because alien-tech... pretty much falls under the plot devices of Torchwood, UNIT, Dr Who, and SCP. Except we don't have a timelord tour-guide on this little sojourn.

--There is a caveat.
A more advanced level of primitives may find themselves [u]not[/u] subjected to genetic tampering... as a sort of inverse prime-directive of sorts where if they've actually hit a technological milestone they get left alone rather than treated like cattle and breeding-stock.

[i][b]Titania may have crashed at some point on such a planet and garnered a cult-following.[/b][/i] Leading to an odd situation where an underdeveloped race is aware of the MGMA, but probably does not entirely understand their existance.
--Independent tech-tree means they may have come up with how to shrink/grow their monster-girls... which also allowed for them to build nano-machines at enlarged sizes before shrinking them back to operational sizes.
