H-Bridge as a 4 channel relay?

Is there any reason the H-Bridge couldn't be used as a 4 channel 'relay', to drive only one output at a time (with the added benefit of voltage level control)?

I would like to control 4 different valves, but only one of them at a time. They all have a common ground, so I thought this would be a good way to control the input voltage.

Thoughts?

Not by design, the output pairs are either +/- or -/+ or off.
