Yes. A hypothesis is nothing more than an assumption or a speculation, albeit one that must have reasonable grounds. Once it is supported by a good amount of data (as you say any good hypothesis must) it is then a theory and no longer a hypothesis.

As I said before you started getting whiny, if you only test things that are already supported by a lot of experimental data (theories), you aren't going to get anywhere.

Hypotheses should NOT be so good that they don't have to be tested. That's the entire purpose of experimentation, to enter an experiment with several hypotheses about possible outcomes and then toss out the ones that don't work. Extensive engineering does not go into a hypothesis, engineering goes into a working theory.
