Why not try (make) a light tent.  You can get them commercially, but after
looking at a few, it might be better to make your own.

Basically, it's a tent made of white cloth (sacrifice a sheet or two) that
encloses the subject and at least the objective lens of your camera.  The
lights stay outside the tent, shining on it, and the cloth diffuses the
light very evenly across the subject.  Without an effective point source
of light, the hot spts go away.  (Of course, it isn't likely to be perfect,
since some of the light will go straight through the cloth rather than
being completely scattered, but it should be a great improvement.)

You'll probably have a drop in light intensity on the subject of about
one f-stop, maybe two, depending on how thick the tent is.

I built one to cover a fairly large object once out of PVC water pipe
and PVC fittings (pressed together, no glue), and hung a couple of sheets
over the frame.  Worked fine.  Also used all the lights I had at the
time.  And most of the living room.  Kids loved it.
