However, like many things in Endwalker I do believe they're just referencing things from FFIV directly and have no link to current moogles, but hey, who knows?
Actually, Hummingways were always rabbit-like, even in their sprites. So it may be a case of one thing influencing another and then said thing reinfluences its origin. Hummingways were the inspiration for Ivalician moogles, but during the redesign the mooglrs influenced the Hummingways.
