Racial Heritage and feats that assume a specific ability?

OK, so... Racial Heritage(Kitsune) lets you qualify for feats as though you were a Kitsune. Fox Shape requires Kitsune, but doesn't specifically require the Change Shape ability. It grants the ability to turn into a fox as a standard action (and presumably back...), including... essentially all mechanics of the change right there, other than specifying it's Su (which it ... probably ... is...). Swift Kitsune Shapechanger lets you take on Kitsune or human form as a swift action - no reference to Change Shape either (and may be necessary for getting back to human form from fox form).

Would that actually work?

Note that this isn't true of all such - Realistic Likeness specifies "When you use your change shape ability" - so you could qualify for the feat, but explicitly can't use it unless you use a named "Change shape" ability. Funny....
