since "elites" have three pluses/minuses, "professionals" have two, etc., stands to reason that "legendaries" would have four, right?
pytaekhammerhead (looks like eradicator, with the tip even more exaggerated to fit the name):
-3 range, -1 damage, +2 mobility, +1 fire rate, free foregrip
the mobility buff would essentially equal quick draw; a fire rate buff with no penalty to accuracy (like the insanity) would be an interesting trade off for the nerfed range n' damage.
IMR psychopath
-2 damage, -2 accuracy, +4 fire rate
eight round burst, fired in the same amount of time it takes the stock version to fire four.

akimbo sn6's
ASM1 hellfire
flamethrower (!!!) in exchange for the disallowance of other underbarrel attachments, including foregrip, which is no small sacrifice. the flamethrower would be similar to the ohm shotgun in terms of range n' damage.
XMG go-getter
akimbo remains, however instead of locking down, one of the guns may be ADS'ed.

-3 accuracy, -1 range, +4 damage. yeah, buddy.
RW-1 snuffaluffagus
exaggerated barrel resembles that of (nicholson's) joker's revolver used to shoot down (keaton's) batplane. awkward to aim, massive kick, but one shot kill, unlimited range.
this is fun. thanks for the post, bane!
