Default Using a 6X4

I'm about to build a Aikido pre-amp and am planning to us a 6X4 rectifier in a LCRCRC psudo dual mono configuration. My PT has only one 6V heater output and will be used thoughout the whole pre-amp. My questions are:

1) Will this cause some hum issues due to having the rectifier and amp tubes sharing the same AC heater lines?

2) If I use all AC heaters, can I raise the heater bias on the 6X4 to about 70VDC?

3) Can I use DC on all the heaters including the 6X4?

The last resort would be to just aquire another TF to split off the rectifier from the rest of the amp but that requires another trip to the store. I'd like to use what I have in my junk box.
