Can I switch the Third Person Character blueprint with another Third person bluprint?

I recently downloaded a free quest system to my own computer. I was hoping to use some of the dialogue assets from that level. However, the quest level already has a third person character implemented, complete with blueprints and capsules. I was wondering if there was any way I can change my third person character with the third person character of the quest level without copying and pasting all the blueprints?

It really depends, if the blueprint has functions and variables required for the dialogue system to work, I would say no. If its just the default 3rd person character, you can change to yours in the game mode.
