Assembling this mass into a ball presents a problem, as
we talked about. Maybe consider injecting the mas into a
low Sun orbit (LSO), then do the assembling into a sphere
with a crust.
Leaving it there in orbit, go out to the Oort cloud and gather
up a roughly comparable mass of whatever. This can be accomplished
with relativly little energy expenditure. This mass is now sent on a
long-period cometary-style orbit which intersects the orbit of the
fusion-primer sphere. With proper mass, timing and flyby distance (prograde,
passing behind the sphere) the sphere's orbital velocity is nearly cancelled,
allowing it to drop nearly straight in, as desired. The cometary mass
takes up a Solar orbit of higher angular momentum.
A variation on this is a combo shot: Drop the Oort cloud mass(es)
on orbits intersecting the big moons of the gas giants, either putting
them into periodic solar orbit or straight in.

99% of the Sun's helium-3 was down below

And do the same here. A good deal of He3 can be obtained from the
gas giants, maybe enough to make this a one step procedure??
