Will this work? Switching from 6.3 to 12.6 volts

I was looking for some 6x4 rectifier for my eico st84 preamp which i just finished rebuilding. I found that i have quite a few 12x4 but no 6x4. the eico uses 6.3vac heater voltage. So, i wondered if i did a voltage doubler circuit with the 6.3 and appropriate rectifiers and caps if the resultant DC voltage would be adequate for the 5 12ax7 tubes and a 12x4 rectifier. I would have to rewire the sockets for 12 volts.
I know a lot of you are thinking 6x4 tubes are pretty cheap why go through all the trouble? As a matter of fact i am going to get some but still i wonder for argument's sake if this is a valid thing to do? In case i have a situation where i needed the lower noise of DC heating of the preamp tubes. Cheers, Dak
