They should be OK the 916 and 996 both have 50mm throttle bodies as standard. Better option could be a 748R shower injector setup which uses 54mm throttle bodies.
Even the 748 has 50mm throottle bodies as measured at the butterfly, they then have a 44mm restriction downstream to comply with the Supersport regs as they stood at the time.

Cheers for that chaps.
What about getting my 748 bodies bored out at the 44mm restriction? Is this straight forward? Can any engineering firm do this or is it best left to a Ducati specialist?
You could probably get 748 ones bored out at some cost but there must be quite a few sets of 916 ones around that should offer a cheaper alternative. My 996 that I am building at the mo has the standard twin injector throttle boddies but I do have a 748R set of 54mm shower injectors along with airbox that I may see about fitting futher along the line. My 998 uses slightly different 54mm shower injection and that works fine so a similar set up onthe 996 may be the way to go.
Incidently my 955 engine has a 54mm twin injector setup
Sigma performance website is always useful to look at when considering doing these sort of things, mainly under the technical section. Here is the link with the 748 info
