Had an idea in regards to this, a fun variant if you will. It's a bit of a downgrade and a bit of an upgrade.
Lose the XL engine, drop it to 10 DHS so you're forced to range-bracket your firing -- and give it TSM making the sword more useful. Move the ammo all to one side with a single case, allowing more of the firepower and functionality to remain when/if you have a blowout.

I'd probably also make a version that loses the AMS for a flamer and two to four light machine guns... or maybe a-pods?
The zombiemech aspect of it makes up for the ~12.2 or so points of damage it would lose in a point blank fight on the lasers -- hanging in the fight another two or three (or ten) turns is just as good as more punch per turn. It would also have more punch in the 3-5 hex range so that may be a wash during closure anyhow.
Inner Sphere XL's in all but the rarest cases feel like putting all your eggs in one basket made of tissue paper that's on fire.
