@Wassup Thunder HM! Sorry I had to think on this one.
When I was thinking of something for Halcyon Hare, TBPH, the thing I was thinking of was the Primal fight against Tsukuyomi in FFXIV. Long story short, crazy lady turns into a big bunny-eared goddess that uses the power of moonlight and darkness to kill you, mostly with her pipe, fans, and two long katana blades. It's a real fun fight. But converting that to a Maverick--if I could've--I'd figure the received weapons for X & Zero would be along those lines.
Maybe a ray beam for X (that can bounce around the area), and the charged up shot releases a dark cloud that can homing beam things on the screen.
Zero's would probably be a split Z-saber where he charges forward with two moonlight blades, and his charged would be a 360 degree spin of blades after the charge forward. xD
Guess it'd also fit cause the small ray-bunny enemies that appear in some MMX games use their ears to shoot beams at you, so kind of makes sense if the big boss Maverick akin to them absorbs moonlight (or maybe even sunlight) to do attacks with. Unsure if the Maverick would be more kunoichi or samurai in style, but it'd be a cool thing to draw I'd figure.
