After I saw Joe Joyce's idea of a 1-step Chess it struck me that the most logical rule for the Knight would be that:
(a) both start as noncapturing Princes;
(b) after moving as a Ferz a noncapturing Prince becomes a full Wazir;
(c) after moving as a Wazir a noncapturing Prince becomes a full Ferz;
(d) after moving, a Wazir or Ferz becomes a noncapturing Prince.
This would simulate the normal move of the Moo, the strongest stepping Knight, spread over two moves. Even so, I suspect that a 2-step Chess - Rook as Wazbaba, Bishop as Fearful, Wueen as Pasha, rest as their FIDE selves - would be far closer to FIDE Chess as Wazirs and Ferzes are switching pieces. In fact I would even venture that 1-step to 2-step would be a bigger step back to FIDE Chess than 2-step to 3-step - Rook as Guardian, Bishop as Wrestler, Queen as Liondog.
