Age Change

Back on RE:CN, I created Zeo as a thirteen year old kid, which was ironic, seeing as I was eleven at the time. When I remade him on RE:RN, I recall someone saying it was seven years later, so I made him 20. Despite this, roleplaying a 20 year old guy doesn't really suit me, so would it be okay to change his age to 16?

Again, that's two years older than I am now. Sensing some kind of pattern here.
