If it'll work, it'll be a whole lot cheaper to buy an Aqueon versa-top and have the sides cut off
The hinge and back strip are plastic so they're easy to cut
And anyone who can cut glass can trim the width to size
You could even just replace the back half of the glass to get rid of the back plastic strip
Make a cardboard template of your top and take it to King Ed's to see if a bowfront top will fit your curve
