On BB, the general message is bonding occurs between two, fixed rabbits who go through prebonding, dates, supervised time, etc.. it can take months.
Since the rabbit will only be 8 weeks old, it would be most safe to keep the rabbits separate until the young rabbit is fixed. Hormones play a big part in bonding. Young rabbits will get along with any rabbit generally because they don’t have hormones driving mating or territorial behaviors. Initially, this is why a lot of people misunderstand and believe young rabbits are bonded. The danger of trying to bond an 8 week old to your rabbit now is that it may seem to go well, but you have no idea when the young rabbit will develop hormones and once that happens, a morning of cuddles can turn into a very dangerous fight while you’re sleeping.
I’m assuming this is not what you wanted to hear (you need to wait to bond), but it would ensure the best happiness for you and the buns.
