I like all your combos except
Dorothy Eve - the 2 ee sounds next too each other bothers me.
Dorothy Paloma works I think because the names have different rhythm - DOR-o-thy pa-LO-ma. Two names with the same rhythm, ie
Dorothy Abigail, doesn't sound great.
Dorothy CamilleDorothy JanelleDorothy LynnetteDorothy NadineDorothy CorinneDorothy CelesteDorothy SeleneDorothy CeriseDorothy LorraineDorothy Yvette
Also, I love this site about middle names:
