Attempt to get the FATTEST spark plug arc

Proposal:
I was disappointed that my MSD6Al only puts out 1 amp per 1000 rpm. It's and adequate spark but I want a fatter arc.
Idea:
Add a second coil, fabricate the 2 coil wires into 1
QUESTION:
Would there be energy enough of a significant voltage drop if the coils were wired in series ?

At 6200 rpm the amps from the MSD is 6.2.
Which I'm thinking is not enough to feed two Accel super coils

I know that I could run the risk of overheating the coils, but, I would use one coil to cruise, and if somebody revved the engine at a stoplight, engage coil two for the duration of the run, the disengage it.

Idea 2
2 MSD boxes, 2 coils, as before 2 coil wires fabricated into 1

Potential problems with Idea 2
Can't run wire core spark plug wires with on
an MSD6AL Box, it will fry the box
So...I will have to run non wire core wires.
I don't know if the insulation on the non wire core wires will do 15 amps total. I'm thinking there is a spark plug wire cover can get that could reduce any chance of electricity leaking and arcing on the engine.
Also I'm thinking that the arc off the rotor could be enough to hit two cylinders at once ??

Biggest challenge:
Fabricating the 2 coil wires into 1 coil wire without leaking current
