combining flight template with 3rd person template into one game?

I want to combine flight template with the 3rd person template!
example = flight template for external ship and 3rd person for inside ship feature. I want to be able to switch between them in game.

I confused on how to accomplish this goal! theirs one game mode per lvl. any thoughts or direction on what to study would help clear this up.

is it even possible?!

you can achieve this easily .
just create to void project (1 for the flying template, 1 for the 3rd person) then export the game mode and the asset you need from each project to you project. and just change the game mode using BP when calling your level.
