When this pops I'm definitely picking some up. Question I have is, can I use an NPN germanium? Would it be as simple as removing the voltage inverter?

Pretty much - leave out all the parts involved with the inverter and reverse any electrolytic caps. Not having built one I'm not sure how you would connect the DC to the circuit but it shouldn't be too difficult to work out.

Might have to put a jumper from pads 1-5 on the tc1044 spots but it should be doable

Uh-huh. The bias trimmer should be able to accommodate variations in transistor leakage and current gain.
