Unfortunately, I don't think there are any other Taysom Hills. At least not a guy that can throw some, is a great power runner, has great speed, can play as a very good power HB, block like a FB, and run routes and catch well enough to play TE.
Still there are some guys out there that can play multiple positions and do some of what he does. For instance, Penn State TE, Tyler Warren. Doesn't have Hill's speed and probably not a Wildcat guy but can do a lot of things.
The closest equivalent to Hill is probably Jalen Milroe, but he's likely going to go high in the draft so it would be hard to take him unless you think he's really going to be a QB. And even with Miloroe he has the speed and power Taysom has as a Wildcat QB and Read Option QB, but nobody knows if he can catch or block like Hill.
