I'm sure there is a way, but it won't be a drop in affair. The first thing I think of is axles. The inboard joint on the passenger axle is different between the A413 and A604. The outboard joints on both the driver and passenger axles are different between the Neon and Eclipse/Talon. If you figure that out, it will be like an AT/MT swap. The A413 is pretty crude and only a 3 speed. You might also consider swapping in a manual trans. At least that uses the same axles.
