Symbiote katalyst payback?

CiqMCOC

Hi kabam, just wondering if we will be given something in return for the excessive symbiote katalysts. I have maxed out my summoner symbiote and still have over 20 katalysts left. Can we get something back for them after the event ends? Maybe like 100 5* shards per katalyst left over? Or even 50? Thanks.

when you finish symbionte difficulty you Dress him up with These in different Colors...
or buy different movesets from other Champions...

that would be cool.
