Byakuya doesn't seem like the type of person to try and force something like that on Rukia or any other person. I also don't think having an unwilling member of your clan is a good idea either.
Byakuya was conflicted about breaking tradition and rules at this point, not as outright conflicted about breaking rules as during Rukia's execution in canon, but still conflicted about it. I'm assuming that there are civil rights in soul society like I said in my previous post and if there were I don't see Byakuya breaking the laws of soul society if Rukia were unwilling to join the Kuchiki clan in order to force her to.
Forcing the adoption on Rukia would also conflict with his devotion to Hisana and her final wish. Hisana's wish was made most likely with the intention of wanting a better life for her sister and for her to be happy. Making Rukia join the Kuchiki clan against her will would not make her happy. Forcing the adoption would conflict with the intention and spirit of Hisana's final wish even if it didn't conflict with the wording.
As for having an unwilling member of your clan being a bad idea, well think about it. The unwilling person might act rebellious and not be well behaved and they would have a perfectly valid reason for being that way. It would cause problems inside the clan such as disturbing the peace and maybe even the running of things. It would also reflect the status of the clan in public as well if such misbehavior were witnessed by anyone outside the clan, and for nobles like the Kuchiki clan their public image is probably pretty important.
