Character control and vehicle movement

I try to make mount a character (BP Character Class) in a canoe (BP Character Class) but the peculiarity is that I wish the character and the use of his arms in the canoe (take a bow and pick up stuff).
Basically I want to check 2 character class at the same time, each with their own “Character movement” component that I will activate and
deactivate at my convenience

I have a doubt about the technique I use (it does not work -_-) if there is another more simple or more functional ?
I’m interested

Engine version 4.13
