John,
It sounds like what's described here would approximate a horizontal bilge
keel (aka rolling chock) on each side of the keel, if I read you right.
Properly-designed bilge keels are seldom straight, as they must be faired to the
streamlines, else they will cause an increase in resistance. Since streamlines on a
given hull form always vary with speed through the water, I'd suggest
consulting a naval architect first, as water flowing along the bottom of a keel, or
anywhere else on the hull, is not apt to follow it in a straight line. This is
a simple task for a NA and shouldn't cost much.
As you mention in a later post, the installed angle of even short "wings" is
also important, as it is affected by trim. That, in itself, would seem to make
them more suitable as boat length increases, as trim differences usually
decrease with an increase in LWL.
Just some thoughts.

I have thought about adding a steel plate to the angle
iron to extend it further out each side and run completely under the keel
thus giving more protection and possibly more stability.
