I like your approach to the forward line, just tweaking it a little further:
StewSmack Daniher RazGreen
BegWalla. Hooker. Langverde
This way we can make Smack tall enough and Stewart more competitive, a Raz that never misses (maybe we need a Josh Daniher), a BegWalla could lead to a permanent Blitz meltdown and Langverde makes perfect sense as a mid forward rotation.
A DaniHooker could be impressive too.
