Dude,....just a thought...but why are you building ships that are (more or less,) "zords"? As much as I love your creativity, this 'Equestria-Class
registers as 'Trek'.
I could see a specially-refit freighter who's basic assignment is scooping-up biological traces of endangered species (upon being specifically asked through diplomatic channels
) to get involved, etc.
A sub-department of Starfleet Science that gets appointed to veterinary assignments as a result of war, disease, increasingly-rare natural disasters, etc. to find compatible homes for species thinning out to extinction as a result of (often bipedal) dominant races' encroachment.
