Can I put two male rabbits together if they've been 'done'?

I have a English erfly rabbit, he's now about 10 months old and my dads friend from work owns a dwarf rabbit which is 2 years old. She can't look after the rabbit anymore because her dog tries to get it and, like, savage it so she's giving him to us. The dwarf rabbit is getting 'done' before coming to us and ours is already 'done'. I also have 2 female guinea pigs and my rabbit gets on fine with them and actually loves them. If I put the dwarf rabbit in the same hutch as them, do you think they'll get on fine since they've been done? Please reply, thank you.
