I've overdriven t8(which t12 should be similar) before, and it does work, but it shortens lamp life.
Could you get a picture of your wiring and ballast information? That would help to see if it's a wiring or ballast mismatch issue (which both can lead to dead lamps when overdriving).

I do have to ask though, why are you overdriving the lamps?
I did it for a stop-gap for me until I could get a new fixture.
