Not enough voltage for most electrostats.
There are direct drive electrostats that are sort of like what you are describing. But not using the 45 triode. They are using very high voltage transmitter tubes. I've heard of some Beveridge that were done that way. There is a guy named Alan Kimel that is one of the most experienced at this sort of thing, and he probably is at the VSAC show right now. David Berning did a ZH270 for, I believe, Alan Baghan, to directly drive his Soundlabs. It has been done, but it is still kind of experimental, and somewhat dangerous to work with this high voltage.
Interesting concept.
