Are you saying you want to set up one of your flashes remotely? That could be useful if you have some type of modifier, an umbrella or softbox or some such thing.
But you'd also need some kind of support for the flash and modifier, and also a way of triggering it, as in a wireless trigger.
But, you can get a good flash bounce by having the flash mounted on your tripod and angling your head up to bounce off the ceiling. The light would "bounce around" to give your subjects a more "diffused" illumination.
And there is another thing you can do, which is to mount a "bounce card" on your flash head. With your head pointed up, some of the light will be bounced off the card to your subjects, providing some additional "fill" as well as some catchlight for the eyes.
A bounce card can be as simple as a white index card partially wrapped around the flash head, or something bigger and more ornate that you could construct yourself. A current POTN thread is discussing indoor flash photography, and starting at post #11 a discussion starts on bounce cards, and a couple posts later someone posts a link to a "Do It Yourself" (DIY) Bounce Card tutorial, showing how to make them but also showing the effect of a bounce card. Here's the thread:
