To answer you question, yes it is that easy to make a CC into a BBb. It won't make a great BBb but it is a cheap way. The length of tubing you'll need to lower the horn a full step is exactly the full length of the first valve tubing. However you have another option if your CC has a fifth valve with the flat whole step. You could have it shortened a little to make a regular sized whole step. Then all you have to do is depress the fifth valve and hold it down and your horn is in BBb. You still have to adjust the other slides to BBb length. Also when you use your tuba as a CC you'd need to pull the 5th valve to the long whole tone length.
