Did you ask your friend what she DOES like? That would be helpful!
Ganache is good idea. Also, I wonder if she'd like MMF. It generally does taste better than traditional fondant.
What if you compromise by icing the cake with fondant or bc (whichever you think would work best for her cake), but fill it with your friend's favorite filling...?
Maybe try an IMBC / SMBC - she's probably thinking of a regular American buttercream made with powdered sugar - the IMBC/SMBC have a completely different taste and texture.
How about cream cheese frosting, or even just a basic whipped cream (you can flavor that however you like)?
Royal icing? I was going to say fresh cream but Babycakes bet me to it
