Are you asking for Khanid loyalists as in "Khanid Kingdom loyalists", or for true Khanids (the bloodline) ? Because depending on the answers that's totally different.
Since Silas turned blooder and KPV collapsed, I haven't seen many Khanid Kingdom loyalist corps or alliances yes. I don't know either a lot of Khanid Kingdom supporters, be them Khanid by blood, or not (True Amarr, Ni-Kunni, etc).
However, there are many Khanid loyalists, as in loyalists of the bloodline. Most are Amarrians though, not Kingdom loyalists.
