So, all other hangar pets in the game are very similar if not identical to their playable versions. The BoP hangar pets look just like the player models, as do the Peregrine Fighter, Stalker Fighter, Runabouts, Scorpion Fighters, etc. The only hangar pets that look nothing like their playable counterparts are the Jem'Hadar Attack Ships and To'duj Fighters. Currently, both hangar pets use low-quality models with very little detailing, which means there's room for improvement.
Exhibit A is the To'duj Fighter. In the screenshot below you see the non-combat To'duj Fighter pet on the left next to the current model of the To'duj Fighter hangar pet on the right. The non-combat pet looks exactly like the playable version, while the hangar pet is significantly less detailed.

Seeing as the two models are the same size and the more detailed model already exists, I don't see why the current hangar pet model couldn't be updated to the higher-detailed version.
Exhibit B is the Jem'Hadar Attack Ship. The current player model is very much true to the ship's appearance on the shows, while the model used for the hangar pet is substantially less impressive. The first image is that of the current playable ship model, the second is that of the hangar pet.


Just like with the To'duj, would it be at all possible to update the hangar pet's model to that of the higher-fidelity player ship's?
This is rather nitpicky, but honestly these changes would be a nice and, as far as I know, easy change to make to these two hangar pet models. As mentioned previously, the models already exist in-game and there's no rescaling necessary, so why not? Please feel free to post your thoughts/comments below! Thanks for reading!

I don't see the "low-fidelity" versions as being much less polygon intensive. Certainly nothing that will impact anyone's performance should they update those to the "high-fidelity" models shown, even if they play on a toaster.
Nitpicky perhaps, but I can understand the point here. There is no reason to have both a low and high quality version of the same model when the trend (apparently) is to have the same model for both pet and hanger. Not sure why it isn't like that already.
Also, I wouldn't exactly say the Jem'hadar Attack Ship hangar pets are small, LOL. Same goes for any Frigate-type hangar pet.
