Listen to L. Johnson's Bedbug Blues. I think you'll hear more post-'62' B.B in there than you will in any T-Bone recordings. T-Bone and L. Johnson were similar only in the sense that they were both hugely influential. I don't recall what song or songs T-Bone may have used the B.B. signature lick on, if any. He sort of hints at it in the head to "Two Bones and a Pick." I still think his influence was wider with the Texas and West Coast guys like Pee-Wee Crayton, Gatemouth, Collins, Pete Lewis, etc. than with any of the modern Mississippi and Chicago guys. Mississippi was listening to what was happening in Memphis, and to Louis Jordan, while the Southwest and West Coast seemed more focused on Kansas City and Count Basie. By the way, I think that Chuck Berry lick you mentioned came to him from T-Bone via T-Bone's efforts to imitate Lester Young's tenor.
