So... what colour should I paint these blades to make it more futuristic? Not sure whether to go all the same uniformed colour or make them various bright blues, yellows and green to make them like light sabers.

I will eventually port these to long rectangle stands and pad it out a bit with Ork Boyz with guns.

Who do you think should be the Ork boss out of the three in the power armour?

I would paint them standard gummetal. Orks dont usually use powerblades and your weapons doesnt look like them, they look like more ordinary weaponary.

About the boss, the hammer guys is my favourite.
