Unduped 5* Hyperion to r4?

I have a few 5 star champions and recently got a Hyperion. If I rank down my unduped captain marvel back to rank 2 I will have enough catalysts to take my Hyperion to r4 as my first r4 champ. Is it worth it?

You should download/look up Seatin's Tier List... it really helps to know which need dupeing/awakening and which do not.
