There are only 7 engines (not counting the DC engines) from the Waves 1-4 blind bags that aren't available in the original 3- or 8-packs. Spooky Percy, Spooky Diesel 10, and Ben are 3 of them. Golden Thomas is another, but of course he's available in the Collector's Wheel. The other 3 are Heroes Thomas, Racers Dash, and Bill. So I'll be surprised if CHL73 doesn't have those engines.
Those engines also match up with the hierarchy I mentioned in this post, so I think these last two 3-packs were probably planned from the beginning, and my guess about another 8-pack was wrong.
