I don't think Elliot is the player we need to replace as the final piece in the Premiership puzzle. Personally, I can see Elliot being part of a Premiership-winning 17, especially if he's on less than 500k a season. I'm not saying he's the best lock out there, but he is a sensible part of the puzzle.
We need players who will make a bigger impact. A dominant prop and probably three spine players are essential. Crossland is good enough at 14, but we need a proper hooker and two quality halves.
Moving on from Hastings and Brailey, who are on much bigger contracts and offer less, should be a higher priority
