Imo, Dorna/Bridgepoint should spend a lot less time turning MotoGP into a production series, and a lot more time differentiating SBK from GP while promoting motorcycling in general.
SBK should move to a new displacement "base" at 800cc for 4-cylinder engines and 1000cc for twins. Supersport should be 600cc triples and 750cc twins. I would like to see a third class for 400cc twins and 500cc supermonos. The purpose of an 800cc base is straightforward; get SBK away from MotoGP, and create a new capacity that makes it easier for the MSMA to pass Euro emissions and American noise standards. In addition, use engine scaling so the manufacturers have more interchangeable parts. Strengthen the homologation standards so the parts on their SBK must trickle down. For instance, the piston, intake valves, exhaust valves, cylinder, rods, pins, etc are the same on the SBK as the SS and ST. For twins, the trickle down could be from 1000cc twins to 500cc monos. Maybe even specify inline layout for 3s,4s, and free engine layout for twins. Homologate tuning kits and electronics for every bike, and specify certain attributes like static compression ratio and electronics strategies. These rules would also be beneficial for the TT championship that is supposedly on the horizon.
MotoGP should remain full prototypes. 16,000rpm, 24L in MotoGP with almost no other restrictions. Moto2 600cc full prototypes 16,000rpm 24L with 4-cylinder rule and Spec ECU with limited stategies. I'd prefer 750cc, but the 600cc I-4 engines would be left without a seat when the music stopped. MSMA will never go for it. I guess Moto3 can stay the same as it is now, though I'd prefer 500cc prototypes 16,000rpm twins or some such. MotoGP should be creme de la creme pros, not children who should be in high school (even if they are amazing).
Moto1? I hope not. WSBK-MotoGP merge? I really hope not b/c the manufacturers aren't going to sell GP bikes or anything close at an affordable price. Keep the series separate and make sure FIM competition has at least 150 seats up for grabs. Motorcycling will need them when India and China get involved.
Anyway, it's the off-topic season.
