"Harmonizing" the :height attribute for multiple faces in the same string?

"Harmonizing" the :height attribute for multiple faces in the same string?

[Bastien]

Dear all,

given a string combining various substrings each with a different
face, each face with a different :height attribute: how can I set
:height to the same value for all faces in this string, keeping 
the faces (and their attributes) distincts ?

The use case is this: when navigating Org headings, the minibuffer
displays the heading the point is on, but when users customize the
height of the various heading levels (org-level-1, etc.), then the
displayed heading in the minibuffer combines multiple heights,
which is ugly.

Any help appreciated!

Thanks,

Define new faces, each of which inherit from the one of the respective
substring, and then override the :height with set-face-attribute?

Alternatively, does add-face-text-property help?

How 'bout `add-face-text-property` with a face that specifies the :height?

I ended up using such a solution, thanks a lot for putting me on the
right tracks!
