Getting smother bunny would probably be a really good idea because they are usually very social
I had two males but my older one passed away and my younger one got depressed because of it so I had to get him a new bun right away and they bonded pretty easily.
Although your bun is at an age where he will start getting hormonal and therefore peobably territorial and most people suggest keeping the buns in separate cages next to each other and do pre bonding until they are both fixed and have a month for hormones to die down
Otherwise the bond might not be as strong after they are fixed and there is more danger for fights breaking out because of hormones making them territoral
For pre bonding you switch the buns between cages once a day (with all the other buns stuff and litter in it) to get them used to living in each others territories.
They should be able to see each other and eat in an area they can both see each other from
