kyomu , is all honesty Sev really has never trained for longer than 4 - 5 months at a time be it on gear or natural.He seems to focus on it for a while then goes off and finds somthing else of interest to him..I think the pics he posts are truthfull of this as some he is clearly not training..
For someone who only trains for short bursts he gets into good shape pretty damm quick , if he was to train full on for a year I think you would be very shocked at what he presented on stage and with his height advantage I think he would take you..
A year is a long time though and will Sev do it? only he will be able to answer that , maybe up the prize money a bit more to really make it worth his while and then you will have a real fight on your hands , just me being honest.
