I would like to see if Cat , Saili and perhaps even Clifford get back and have a meaningful contribution

Recent long term injuries haven't gone well .. Winston Stanley , George Lowe spring to mind , and Sam Twomey and Harry Sloan still aren't troubling the selectors at Irish and Ealing respectively

As you've said in the OP PG doesn't seem too keen on Lewis Visser Alofa Luamanu - I would add Archie White to that list .

I think Luamanu is a good back up second row -ours seem to be made of china recently
