Probably intentional, the same year also had this ikeda character in a megaten title. Theres actually quite a few gundam references in megaten, to the extent I start getting a little paranoid schizophrenic and pull out my pepe silva dartboard out to try and determine whats a reference and whats not.
100% confirmed intentional gundam references
>Kaneko described the bit balls floating around SMT2 machine Medusa as mobile suit bits
>Kaneko said Cybelle's original devil summoner color scheme is based on the gundam mobile suit Qubeley, which itself was named after the goddess Cybele but just had the romanisation butchered (キュベレ vs キュベレイ )
>Shido
>The Persona strikers character sophia has a pseudo persona that splits into drone like objects that fly around, internally the files refer to these as "funnels" after the mobile suit weapon
>Rob roy in the persona gacha is a china knockoff SD gundam
Then for the not confirmed as intentionally references but I'd be willing to bet are
>SMT1's angel colour scheme being based on Lalah sune, a character herself often represented with angel and wing imagery
>Dagda Char
>Nahobinos finger swords form in the exact same way as, and have the same pool floaty physics as the garazzo's beam claw sword from gundam 00
