Serafall Sitri is no longer Serafall Leviathan you know ? If she comeback and Sona already inherited the house she wont be in any political position unlike Gabriel who is the leader of the Heaven. We also dont have anyone who is a Ice magic user in the harem.

I could see Ishi pulling something like : Ajuka had to send Serafall Sitri outside the seal because she collapsed due to her Sona-tan deficiency or that she need to manage her little sister's groom candidates.... Since Sona will inherit the position and her parent will probably want her to marry.

As for Grayfia ? As much chance of getting into the harem then Lady Phoenix or Venelana Gremory. So, 0% ! Come on guys...
