Sounds like a good idea and it seems like the simplest method to overclock the Yamato. I'm just waking up, so that's all I can think to add. But I say we go for it. The Amalthea-class with its GN-Drive(s) [i]should[/i] be able to produce a powerful Wave Motion Gun. 

EDIT. Also I think its safe to move on [@Crimson Lion].
