Not really, if you look REALLY closely at the Vf-27 and how it transforms it's actually identical to the VF-25, which in turn is actually more like the YF/VF-19's transformation
The similarities between the VF-27 and the SV-51 are all purely cosmetic. The three toed feet, the funky canards, and how the torso and winds look in batroid mode look similar, but they don't transform in anywhere near the same way.
