I did some extra calculations, it seems that electrons have a centrifugal
accleration of about 1E10 m/s/s when rotating about an atom-core. If we are
going to accelerate things so fast, atoms are going to be ionized. This
means no ordinairy matter could be used.

So in short, you use a accelerator build up from several loose cannons in a
path spaced through our Solar system.
Changing the distances between accelerations may decrease the mean
acceleration but not the instant acceleration. I think it is the latter that
we need to be concerned about.
Your idea sounds good, but can the lasers correct the direction of the 100
