Do you choose between the missile packs? It's overweight as it is.
edit: Also, why ORYX2 and not, say, COUGAR2?
Anyway, here's what I'd do to it.
Core: YC07-CRONUS --> CR-YC99UL (0,0,5,5,0). 99UL is pretty much the same as CRONUS except that it has AMS!
Legs: LR03-ORYX2 (keep if you like it. But just wondering why not COUGAR2... or even FA?)
Arm Unit R Hanger: WR08PU-ROC PULSE RIFLE --> None. SHADE shouldn't run out before they die.
For Optional parts, consider AMINO, ES, SS (essential for RJs!), EC (for KONGOH!), L+, CODON (or PHAGE if you prefer), and R+ (for EYE3!)
