Hero Costumes Discussion

[Guvnor]

Not 100% known but i lean towards no.

someone made a new thread about this here:

Is it possible to use a costume version of a hero separately in Alliance Wars?

Is it possible? For example I got the Boldtusk chef costume. Can I use Boldtusk in my first attack and then chef Boldtusk in another attack? (Sorry if it has been asked before and also for making a whole topic about this.)
