I think you should certainly see the steals. He may even get the 10 AB. Who knows, a few hits doesn't seem impossible, with his speed any grounder has a chance, maybe he can even bunt (or learn from Stubbs ). Yea, you might be dreaming about the XBH, but who knows.
To me ultra-fast players are always valuable. Maybe it was my complete lack of foot speed that fascinates me about them, but I would love to someday see a repeat of the glory days of the mid-80s Cardinals. With the bigger bags I actually think those days may come back in the next decade where a team loads up with guys that are a constant threat to steal.
I lived in Pensacola for Bilky Hamilton's near 200 SB season (over multiple leagues). It was exciting, he simply could not be stopped at AA. He had a pretty good chance of stealing the bag if it was a pitch out, if it wasn't the defense had no chance at all to get him.
