i do not think the loose toner would be practical, alignment and all.
I remember one time it got stuck and i manged to rescue the printout by  
running it through the fuser i use for transfer.
I do not see what the advantage would be of keeping the toner loose, how  
would you get it on the PCB without simultaneously fusing it to the paper  
anyway?
Do try the silicone paper if you have trouble with release. I will do more  
experimenting soon, with neutral-curing silicone i got a few days ago so  
there are no acetic acid concerns.

i don't think you can print twice with a laser, inkjets are better with  
alignment.
