An example for an ancient compound with rhotacism carried out seems to
exist, namely: Q _Tindómerel_ *'daughter/child of twilight' (V:385)
with the primitive form given as _tindômiselde_, root SEL-D.
But in the context of _Mondósaresse_ this discussion is now pointless
anyway - the note from "Quendi & Eldar" Andreas Johansson pointed out
in message #950 should have the most relevance here, I think.
