Am I asking for too much at my baby shower?

So I'm having twins and my baby shower will be in October, one of the ideas I thought was really cute was to ask guests to bring a book instead of a card. Then I also thought about doing a diaper raffle game, which is optional, but I feel that's asking for too much? I'd really like books for the babies but I'd also really need help with diapers as there are two of them. I just don't want people to feel obligated to bring diapers on top of a gift and book. I think I'd be having two baby showers as Bubby is going to be locked up and will be out in November and he wants to invite his side of friends and family that I really don't want to mix with my friends and family. If we don't have one from his side that's totally fine, but if we do then I could always just do either the book or diaper raffle at either one. But doing both at one shower would be too much right? I'm not just expecting to receive because I want to have games so people can win prizes. I'm inviting about 40-50 people all whom are very close and I keep in touch with all the time. I'm not too reliant on having two showers as I'm not sure Bubby will still be in the picture once babies are here. Any thoughts Please? And ideas for prizes? Also for baby showers are there just finger foods or an actual filling meal?
