A Dream? or an Idea?

I had a strange dream last night that I was fighting along side Ryo
and then we were sucked into some kind of time portal and appeared 15 years or so
into the future.  

We saw Ryo older and with blue highlights in his hair. (like at the tips of his bangs)
After they saw each other I woke up x'D

This gave me the idea to draw Future Ryo, when he's around 30 or 40 years old.

Should I do it?
