Electronic Ignition

Hi All!
My Sonerai is currently equiped with dual ignition. I've got a slick
magneto running off the flywheel end as well as a normal stock
distributor (that has been shortened somewhat and fixed timing) in
the normal distributor location.
The thing I don't like is the magneto hanging halfway through my
firewall as the Sonerai has the 1835cc VW motor mounted almost right
up against the firewall.

I want to make a new firewall, but I dont like the hole in the
firewall for the magneto.

Given that I hand prop the motor to start, I'm wondering about the
viability of maybe replacing the magneto with an electronic ignition
setup.
Question...?
What electronic ignition options are available that could run from
any location OTHER than the normal distributor location?
Would I save significant weight on going from magneto to electronic
ignition?
How do I get the ignition to fire on TDC for starting and then
advance to whereever once the engine's running?
Is this whole train of thought worth considering to start with or am
I just being stupid now and should live with the hole in my firewall?
Any thoughts welcome?
Regards
Andre
