Pneumag Alternating Double Barrel design idea

[LK-13]

Ok guys,
I've been chasing a double barreled design that shoots one barrel at a time alternating right to left, or left right if you must, the order is irrelevant.

I'm thinking this set up should work but not 100% sure.
so I'm throwing it out to you pneumatic brains of the AO!
check out the design, see if in your opinion it should work
if not then suggest how it may be altered so that it will work.

I'm throwing this out there so that it will be public domain and will stay that way so as to promote growth in Paintball!

just call it the LK Double Trouble system or something like that is all I ask.
don't think that's too big a deal is it?

Trigger Pull activates MVS-2 1-A
MVS-2 1-A activates Fabco PAN-x-5-ODR striking/activating MVS-2 B
MVS-2 B activates MPA-3 B tripping sear shooting barrel one

Trigger release de-activates MVS-2 1-A
Fabco Pan-x-5-ODR spring returns piston striking/activating MVS-2 A then returns to rest position
MVS-2 A activates MPA-3 A tripping sear shooting barrel two

That should work. I would probably try a true 4-way, which I think would do the same thing. I guess a spring loaded cocker "3-way" would do it right off.

Just use a mac 43 series solenoid or use a 4-way.

Just use a mac 43 series solenoid or use a 4-way.
a mac 43 solenoid would be adding electronics yes? no?
I don't want electronics on the gun.

A true 4 way would be thesimplest way to go.
just hook up each output to a different MPA
