The flyback has a ferrite core going down the middle of the windings
and extending outside to form a large 0. This large 0 is made with a
split which is held together by a large U shaped spring clamp. Is the
external portion where to wrap these new primary windings around?
The crack (from falling form the workbench) is the ferrite and is all
the way through. The large U clamp keeps it still in one piece. Do
do think it would be ruined?

I have seen several circuits as you have described. I plan to

and open up the plastic flyback housing and see if it is possible

add some primary windings easily.
No! Do not damage the housing. There is nothing you can do inside
there except break the insulation and wire. The secondary is on the
outside layer.
Put the extra winding on the ferrite core. These extra primary
windings are usually added on the core opposite from the current
windings.
BTW, did you say you dropped it and cracked the ferrite? If so, it's
ruined if there is much of a chunk missing. You may get some use
from
it, but I would not count on too much.
If it is a minor chip, don't worry about it.
Keep in mind that you are talking about generating lethal voltages
which can jump several inches through air, or travel -much- greater
distances along something as innocuous as a chunk of wood.
