To be totally honest with you you should be just fine making a bracket and gluing to the stock ribs.
Are the ribs in this plane comletely solid with no lightening holes in them at all? There is no way to run a wire through the ribs right now??

If you look at post #1 you will see that there are no holes in the ribs. You are probably right about not needing to reinforce the ribs as Goldberg built them tough/strong.
