There are a few champs I think are worth it as 5/6* rankup tandems. Warlock was for me, as well as Torch, Kitty, Peni and CGR (all of whom I have as max 5* and R3 6*). There are probably a few others (AA maybe, Doom, Apoc, Nick, for example) I would put into that category. I only have Shang as a R4 5* and do not use him, so I don’t feel qualified to comment on him.

Dr. Zola Would you add corvus to that list?
