I'm very partial to the theory that multiple magical effects combine in 
unpredictable ways (just like what happened in the train with that 
discusting Draco in GoF). Following that reasoning, taking a polyjuice 
potion when already in the effects of another would have unpredictable 
results: you'd be half-and-half, for example. And the worst thing is 
that the effects wouldn't have to disapear in an hour: remeber when 
Hermione drank a wrong Polijuice Potion? It lasted her for more than an 
hour, which means that even if the *correct* PP last only for an hour, 
a *wrong* PP potion can have an extended duration (I'm willing to say 
it could be a permanent effect, since Pomphrey had to operate Hermione, 
or at least use othe poultices and then bandages).

Hope that helps,
