If I may add to this.
This bike will be very sensitive to swing arm angle of attack, ride height and wheelbase. Changing sprockets can become a nightmare.
We deal with this on our race bikes all the time. I had the worst time with the 1198 SP. That said it can be done.
Typically on the ducati to maintain bike geometry or to even optimise it it will be necessary to go BIGGER on the front sprocket, then even BIGGER on the rear.
Here is what happen with a SMALL front sprocket, your chain goes through a tunnel in your swing-arm, when applying power your chain tries to straighten like a steal bar and because of this pushes down hard on your swing arm squatting your bike and removing swing arm angle. Proper swing-arm angle is critical for drive out of corners or otherwise.
So what we had to do is get a RACE type swing arm that will allow for more chain room ether way, also a bit longer for added wheel base and getting the chain the right size its a mathematical mess.
Because all race track are different they require different gearing thus all these problems. In your case you want to raise your gearing but maintain exactly the bike geometry without causing chain problems.
Good luck, ...wont happen unless you go BIGGER on the front sprocket so you stay off the swing arm, this will require the long chain and huge rear sprocket.
Hope that helps.
