Il FontAwesome random è piuttosto imbarazzante. Non lo userei. L'idea di lanciare i dadi è la migliore da giocare. Ma non mi piace dargli un valore discreto. Per me questo rappresenta quel valore reale. Proprio come l'icona FontAwesome, sembra significare cambiare in modo discreto due elementi. Che è lontano da quello che vuoi.
La mia migliore idea è quella di utilizzare un punto interrogativo e dadi per rappresentare correttamente l'idea di casuale. La cosa che devi evitare è far sembrare un aiuto. Rendendolo quindi leggermente inclinato di lato, per evitare l'insinuazione di porre una domanda.

E un colpo di fortuna che sembrava carino, un po 'come se stessi tirando i dadi e ottenendo "?":
