Oh awesome, yes I definitely subscribe to the thing of him having many kids (most of them around Ash's to Brock's age from when he was in his mid twenties)! I think three of Giovanni's favourite things are alcohol, exercise, and sex. All three are great on their own to him but they also have something in common: they help him get to sleep. I think he has bad insomnia for various reasons.. it explains why he frowns so much, gets bad headaches and is grumpy all the time.
Commandshipping: (Giovanni) It's hard to top the theory you told me, but in one of my HCs Giovanni has like 10-20 kids with various woman and still has something going on with Domino
