Your vet would be the best person to ask, IMO. Has she even been examined to be sure that are no structural issues or inverted nipples etc.?
If the Cane Corso is substantially larger, than she is - then the puppies will likely be too LARGE to pass thru the birth canal. She will probably need a C-Section & the surgery costs UPWARDS of $2,000.00 to 2,500.00. That is a LOT of money!!! (And you may not recover it thru puppy sales since there are many other costs & there may be some puppy LOSS/death.)
If she HAS a C-section, she may NOT be able to nurse the puppies due to having been opened UP &/or may NOT have natural mothering instinct, if she just wakes up & has puppies. I've seen a number of dogs who had a C-section, REJECT the litter, as there was no natural hormonal connection TO the litter, as she has no memory/knowledge of having birthed them, if the vet surgically delivers them. (The rejection doesn't necessarily improve or get fixed, over time.) That means, you will have to force-feed (aka tube-feed) in the beginning, before they are strong enough, to nurse from a bottle. (Not everyone can manage putting a tube down the esophagus INTO the puppy's stomach.)
You will have to be able to feed them & stimulate them MANUALLY to potty (around the clock) for the first 3 weeks. Puppy mortality under this situation, is very HIGH. Therefore, I do NOT recommend breeding her to a larger breed of dog, for ALL of these reasons. If you want a litter, find one of her own breed, to use.
