The Thug is already canon... ^-^ I mean, the only noticeable difference is that you've replaced one SRM6 with a bunch of MLs.
Here's my take on an SL Whammy-2:

The LRM5 is as close as I could get to the Robotech original's rack of "heavy long-range missiles", the SRM6s are mounted under the chest panels.
This mech downgrades neatly to this during the SWs:
