4 lamp F32T8 powering 1 VHO????

[GinKu]

ok i have a 4 lamp F32T8 ballast = 112 watt
and i was woundering if this would work
instead of using 40 watt tubes can i use 1 VHO tube?
right now i'm overdriving my NO tubes to 4x
so shouldn't i be able to power 1 vho on to my F32T8 ballast?
has anyone ever tried this
or am i missing something here?
and if it doesn't work can u tell me why
how does is it different from the WH5
