Could you change Trynda's Ban phrase?

For a barbarian king, him saying 'as you wish' just doesn't suit him (why is it even a line of his in the first place?)

Poppy is more brutal. 'seems like you forgot your brave pants. want to wait while i go get them?'

and Ekko is pure savage, 'you used to be cool'.

Tldr: change Trynda's ban phrase and if nothing suits him, create a new one. How much resources does it take to create one line?
