Would i be able to do rhythmic gymnastics.?

i was wondering if it would be possible for me to be a rhythmic gymnast? i am 14 yrs old. I am pretty flexible. i can do over splits on my left and right side on a chair. i can do middle splits. and like every other stretch. i have been a dancer for 7 yrs. so if i wanted to do you think i would be able to start. or am i much to old? and i used to do tumbling but i can still do like a front walkover and and balk walkover. and other more basic stuff.
