How about utilizing inertial confinement (much like Daedelus)?
Only with smaller fusion pellets - possibly containing the Deuterium and He3
(or Tritium if you can't get the He3 working just yet) caged inside
corresponding (a smaller one inside a larger one) Fullerines?
Spray out thousands of targets and hit them with high-energy lasers,
generating the thrust required.

I have given up fusion research because I ran out of money.
I suggest a fusion engine could be made from a high inductance coil with
its ends attached to copper rings at each physical end of the coil with a
tube of low pressure hydrogen inside.
The reaction starts of by itself if the Q is high enough.
