Not possible to create or modify perspectives on the iOS gadgets at the moment, no. And while there may be built-in views on the iOS gadgets named similarly to the Mac stock perspectives, they aren't actually implemented via those perspectives, so modifying the Mac Flagged perspective (for example) won't make any changes to the built-in Flagged view on iPhone or iPad (though it will make changes to the Flagged perspective on them, so long as the change wasn't to make it a project-mode view, which is not yet supported on iOS).

Hopefully I've just made things much less clear :-)
