Anything is possible
I would suggest that you want to have a lot of confidence in your ability and in your boat, having done some training to an intermediate level would be one way.
Paul Cannel has done the trip several times on a jetski, so size is not the be all and end all.
You would want, in addition to a generally well rigged boat, at least:-
Fuel storage for 120nm at your usual cruising speed,
Fixed VHF radio,
Being able to cruise comfortably at over 25kn is also handy.
