Reason I ask is, you pointed it out - the L-2000 is the obvious choice for nailing the L-2500 sound in a 4 string, but the Tribute L-2000 has a neck like a half baseball bat (at least mine did). If you went USA L-2000, it can be specced with a Jazzy neck if you prefer. Quite a few people went for that, so if you could snag a USA L-2000 second hand, it might have a more Jazzy neck.
The Kiloton will give you some of the L-2500's bridge pickup sounds, but there's no line boost, no treble boost. On the other hand, it has single coil mode which a stock L-2500 won't have.
