Should Samoa Joe beat Brock Lesnar?

Everyone, including myself, want to see Samoa Joe choke the living hell out of Brock Lesnar and become the new Universal Champion. Is it really what should happen from a business perspective?
WWE has spent so much time and money trying to legitimize Lesnar that it has ultimately paid off. Lesnar is a marketable champion and a money maker for the company so it would be a huge gamble to take the title off him and put it on the far more hardcore-fan based liked but not as marketable Samoa Joe.
