As I have studied this pentagonal board myself, I found there is an additional Viceroy move that is limited only on two specific spaces. On further inspection, I found that with an addition of a certain Wazir move, we have a new piece whose movement is perpendicular to that of the Ferz and Boa. A riding form of this piece coud have alternating Wazir and Viceroy steps in a straight line. Combined with the Boa, this could be an analogue of the Bishop on a square board, together with the Hindrattlesnake an analogue of the Rook. As for names of these pieces, I suppose you can come up with any ideas.
