That work. Good idea. Cheaper but more labor intensive.

The hard part is having enough strength  to fold a 36 inch piece of
.065 4130.    Maybe I can use a high life jack under the leaf for
assistance.  I will try in mild steel first.   Jerry

If you make it out of 4 pieces 18 inches long you can taper the pieces
which will reduce the weight and the force required to bend. Tall in the 
middle taper towards the ends. Weld joint in the center. Give me a few 
hours and I will do a drawing. There is an article in this months
Sport Aviation on how a guy used his bi fold hangar door as a press
break.
