A good, simple transformation can be enough for this though. G1 Fortmax forms a really solid looking building that blends everything together smoothly, and Tryp basically flattens out into a very low-profile base that makes good use of its robot aesthetics in base-like features. Metroplex on the otherhand, while having a pretty simple transformation that really doesn't hide anything on its own, has a nice uniform colorscheme that blends everything together in his base or ship modes.
Basically they just need to make sure it doesn't look like a robot laying down
