Lila is nms, but I don't mind it.
I would go for
Lila Topaz, because
Rose is one of the most boring mns in the world IMO (I don't mind it as a fn), plus it looks really flowery, like lillies and roses.
They go fine as a sibset, but like I said in your below post, I would get tongue tied calling "
Topaz,
Esme!", but maybe that's just me.
