Palpatine zeta?

Now, i know hes not a rebel, but stay with me for a minute. Every other legendary character has at least one zeta, shouldnt he, arguably one of the greatest sith lords like, ever, get one? Im not saying game changing, (although it would be nice to see empire in the meta) but something like, both parts of his leader ability apply to sith and empire, or crackling doom deathmarks damaged targets until Palps next turn.

Thoughts?
