Jonathan, you can add an extra piece of acrylic matching the current top, made out of 3/8" or 1/2". You'd probably add it in sections, like a jigsaw puzzle of four large pieces. Beneath these pieces, glue some acrylic railes or strips to them. This will allow the faux top to absorb the brunt of the heat, allow heat to vent out through the gap beneath, and protect your tank completely. You can also replace the heat barrier panels if they become brittle or damaged.
