Yes, but they don't silicone them. I trust glueing plastics together, but I don't trust silicone on plastics.

Hes right about siliconing not bonding to plastic... But this a pretty low pressure situation. It should work fine

Personally I say get them to grind out the glass and smooth it to the 1.5". Then come ip with a plan. I recommend using 1.5" anyways. As you flow water over the weir, the actual water height will be above the edge of the weir. By how much depends on the flow. At moderate flow rate you might only have .25" between the top of the glass and the water if you stick with .75". What were the dimensions you were shooting for in the weir? What flow rate will you have? I'll do the math for you and tell you what the water height will be.
