Having a camera change from top down to over the shoulder on weapon pickup?

Hello Friends,

I am trying to implement a camera system that has a risk vs reward depending on the items you pick up. As this is a maze/puzzle shooter and want the character to lose the ability to see the maze over head when picking up a weapon.

The weapon of course makes the defeating enemies easier, but I want to take the ability to plan out your direction choices a head of time if you have the weapon.

Is this possible and if so, can someone explain/show me how to code this in blueprint?

Thank you so much in advance!!
