Not according to documentation:

       The font used to display the face.  Its value should be a font
       object.  *Note Low-Level Font::, for information about font
       objects, font specs, and font entities.

       When specifying this attribute using ‘set-face-attribute’ (*note
       Attribute Functions::), you may also supply a font spec, a font
       entity, or a string.  Emacs converts such values to an appropriate
       font object, and stores that font object as the actual attribute
       value.  If you specify a string, the contents of the string should
       be a font name (*note (emacs)Fonts::); if the font name is an XLFD
       containing wildcards, Emacs chooses the first font matching those
       wildcards.  Specifying this attribute also changes the values of
       the ‘:family’, ‘:foundry’, ‘:width’, ‘:height’, ‘:weight’, and
       ‘:slant’ attributes.

So maybe you should use set-face-attribute, and only it.
