Adding support to patio cover beams

Hi all. I want to close up the bottom of my patio cover with sheet rock, but I am not sure if the extra weight will cause problems. It doesn't look like the beams are thick enough to begin with. I want to add some support to the beams without replacing them or adding extra support posts. Is this possible? What are my options? Here is all of the info I can gather about my patio cover.
2-(4x6) beams that span 11'4" between 3-(4x6) support posts. (2x6) rafters that span 11'7" w/ 1' overhang, 24" o.c. Roof pitch = 1/12 Roofing is 2 ply peel-n-stick mod-bit under 5/8" plywood. Located in Southern Nevada.
Thank you for any information you can give me.
