Maybe with the LE285? It's 3tons lighter due to 2 from the engine and 1 internal DHS. EDIT: LE285 doesn't work as well as intended. But I made a hotter version with an LE300 Another option like Vergere suggests is to change on of the large lasers into something else Or to drop to an MRM20 The survivability of a LE/STD over XL on a mech with such large side torso's is definitely worth it imo.
Another option is to drop the JJ, and the torso LPL to an ERLL, to give you some range, and get you the engine you want.
