That could work, yes. Saraswati is extremely disappointing for a SSR though, and is literally only good for supporting PF builds.
Notice that your build will be very unreliable when compared to Wind chaingun bursting, though. Aphrodite is "only" 20% trpl+, and Saraswati is 50% combo+ to two characters. So you're strongly at the mercy of RNG. Asherah can give +20 burst to all and Saraswati 25 to one person (and herself), but neither of these compare to the ludicrous amounts of burst generation that Wind has access to (SSR Cybele all the time, Titania with very short but yet extremely potent buffs, Chulainn with a long CD but extreme burst generation).... do we know what the bonus is? To my understanding we only know Hime values, and some Soul values that have been compared to the known Hime values.
