Mmmmmmm im funny on initials too and if i find a middle name i absolutely love and it goes so well but the initials are not the best, i add a second middle name. For example we have a Serenitee and i loveddddd Annaliese with it (Serenitee Annaliese) but with our surname being "D" her initials would have been S.A.D, so we called her Serenitee Annaliese Zayvia and her initials changed to SAZD, yes its a mouthful but i think it flows nicely. So you could do that .

Otherwise, Phoebe Jade is nice
