MFA ideas

So I recently got my BFA, and I don't want to jump into MFA until I have a solid idea for a large body of work... But some of my ideas include interactive artworks involving my persona/vessel. Stuff like giant acrylic dress up with interchangeable clothing, multi-media sculpture, some sort of 3d sculpture box where you're able to look inside... I also want to create large lenticular prints, of course with that I don't know where to start but the idea is there and I WILL find a way when I get there. It's exciting to try to push my art further, but I know it'll be a lot of work so I really must prepare myself for when I decide to go for MFA
