I have a Covert and have made the following modifications which have given me a lightweight rig that meets my requirements. I bought the Covert (at a great price from LP--call them) because the Covert is a rugged, extremely light, back inflate bcd with a 32# bladder, a 16# integrated weight system and two tank straps. However, it lacked pockets which I wanted to carry things like smb, finger reel, signal mirror, flashlight, and dive slate. Also, the top tank band was not a standard cam band (was not as wide as the bottom cam band, and is secured with velcro). To solve the pocket issue, I purchased two Zeagle Sport Utility Pockets, which have two vertical straps on the back side which can slide over the waist belt. I sewed a piece of velcro to the inside of the pocket's vertical straps and the other part of the velcro to the bcd waist ban to keep it in place and as far back on the strap as possible. Works great, and are removeable if I don't need one or both pockets for a particular dive. Second, I replaced the velcro type top cam band with a standard cam band pulled from a jacket style bcd which I am no longer using. The swap out was very easy, and provides a stronger, more stable top tank band where I have added two trim weight pockets that will each hold 5# of trim weights. So far, I have not had any trouble with the D rings, but if they break, I will replace with SS. Hope this helps.
