Need more ways to get Orange Essence

Orange Essence seems to be hard to come by to help unlock skin shards you get from chest.

I feel there should be ways to access/gain orange essence.

two ideas I have:

1 A conversion to convert Blue Essence to Orange Essence ( obviously cant be a 1 for 1 trade , maybe 10 BE for 1 OE ? ) 2 Orange Essence as part of rewards earned through whatever special pass/missions available
