I think Hide's speed would give him early successes and he could hit, but Peter would likely hammer him by the mid-rounds at the latest.
Norris actually beat Tucker but was robbed by judges. Few years later Norris once again beat Tucker and this time he got the decision. Norris was ranked as high as #6 at HW before he was stopped by Bert Cooper.
Peter by brutal KO. I can see Hide landing some explosive haymakers on Sam's jaw, but if a prime Wlad can't dent him then Hide wouldn't either. Peter meanwhile would only have to land a few glancing blows to get Hide all wobbly eyed and marionetting on the canvas. Bit of a mismatch really.
