I will write more later, but it wasn't Frank Jr.'s testimony that sunk Frank Sr.
It was the wire Jr. wore on Sr.
Your theory necessitates Jr. and Toots anticipating that, under this scheme, Sr. wouldn't say anything incriminating about anyone except himself, or at least anyone they cared about, which is obviously impossible.
You realize wires don't provide "live feeds" to the FBI right? Mob rats are known to turn their wires on and off when discussing specific subjects or specific guys. Then they had the tapes to the FBI.
