After reading the question many times, I still don't understand what you mean.
I would just stick with one program. I don't know what WHFS is, but if you want to do that, use its specified parameters. If you feel the program by Waterbury would benefit you more, then do that one and use its parameters.
Generally, the people who write these programs have specific reasons for using the exercise selection, load parameters and rep schemes that they do. It's best to run through a program exactly how it is written at least once and see how well your body reacts to it. Once you get an idea of what parts of the program work for your specifically (and what parts don't work so well), you might start making small adjustments based on your body's preference.
