There's really no need
the F/O on the modern Chevrolet LSX series motors and the Ford Coyote reduce the consecutive side firing issue to just 1 pair on one side. The LSx fires #2 and then #6 consecutively on the right side while the Coyote fires #8 & #6 consecutively on the left side. There is still 90° o crank rotation between them. You can use the same TriY headers as the NASCAR boys do to mitigate even that. My personal favorite is the DOHC Coyote 5.0, though the LSx have their charms, its really hard to top the cam timing variability of a DOHC motor, The LSx substitue displacement and otherwise excellent design for the sophistication on the Ford motor.
The older V8s will have 2 consecutively firing cylinders on each side, crank torsion and vibration is up over that in the modern V8s but you can still live w/ it just not rev as high or as often. here the Tri y exhaust really shines.
The irregular firing pulses do have their benefits, among them is the ability to put power to the ground, HD V twins were notoriously good at powering out of a corner on dirt, The Yamaha V4 w/ crossplane crank does the same on pavement, not sure that this is applicable to 8 cylinders though but it sure does sound good.
