Sekhmet specials don't have armor until Sekhmet comes out, which is .. some-time-I-don't-know-how-long. But they suck as reversals. They are good if you have space and want to keep it / want to move in safely behind your assist, but pretty terrible for gaining space in the first place. Not something I like for Peacock. H.Osiris Spiral seems like her best assist for Peacock to me. Startup is pretty fast, good lockdown, good hitbox, hitbox on both sides, very high chip damage, etc The only other assist I'd even seriously consider would me M.Servant, as it covers AA angle, is decently fast, and an overhead for mixup things. Not sure how good it is and whether it's something one wants to use at all (one will still want a defensive assist, and most of those are DPs which kinda cover the same angle.. maybe with H.LnL in the back or something), but it's something I could see being good. The main problem I'd have with Peacock+Eliza is that both of them have really shit defense, so a lot of your team's worth sits on the third slot; making any team with the both of them very very susceptible to Snaps.
