It's arguably a little bit of a stretch to call Camel/Zebra leaps genuinely short; normally that refers to anything within two king‐moves away (The Short‐range project differs a bit on this, but partly because a lot of those games (especially Joe Joyce's) tend towards even larger boards). So your proposed pieces have the same kind of personality (broadly speaking) as Tamerlane's Giraffe (which in turn leads to the question of that piece's value — might it be comparable to a rook?)
