One more shouldn't be a big deal, so feel free to slap your brother on there!

No, certainly not by the amount of authorized users, unless of course you have like 20+ of people from different households across the country 
You should be fine, even if some of them may have different last names, since any issuers can easily buy information that contains relative information and household members to double-check if they're legit.
The only issue I can see in your situation is if your authorized users spend a lot more than you do, esp if such spending goes ridiculously over your reported income. However, I don't know of any cases in which BofA has done this.
If your authorized users are spending more than you and the total charges don't match up with what your income can support, they might get in touch with you. At least this is what amex does not sure about BoA

I have my credit score up as high as it's going to be without lengthening my average account age. My parents passed on years ago and I have no one else to ask. I'm willing to compensate a friend who would be willing to add me as an authorized user but just cut up the card. All I ask is that they keep the balance low and pay on time. Any ideas?
If you are asking about tradeline renting, that topic is not allowed on myFICO. It's unethical and violates our TOS. More and more lenders discount AU TLs, as they want the applicant to have their own credit profile.
I would suggest starting a thread, detailing your profile so that the knowledgeable people here can give you better advice.
