The news coincides with plans to make Ward the band’s fourth and final recipient of a Walk of Stars award in the city centre.
The idea to develop the tribute came from Dubai-based architect and Sabbath super-fan Mohammed Osama, who said: "If we get approval, all of the stars will be rearranged and the bridge itself will also be named after the band - the band members and their managements have been in the loop as well.
"My vision is to reunite the four original members for the unveiling of the stars and ‘Metal Bench'," he adds. "I mean just reunite them together at their hometown, no gigs or anything – just the four of them being celebrated together at their home town would be the best ending and closure I could possibly think of."
The band played their final-ever show at Birmingham's Genting Arena on February 4, 2017.
The bench will bear the inscription 'Geezer. Ozzy. Tony. Bill. Made in Birmingham 1968.', with portraits designed by Egyptian artist Tarek Abdelkawi. Check out the proposal below.
