tank repair

[bloat]

hello,
i gota 66gal hagen 8mm thick glass tank with a crack in it.
i'm not concerned about what my repair looks like as I will be using this tank for a refugium.

anyway....the crack is on the 48" long pc of glass. It is about 5" from the bottom on one end....is about 20" long....and tapers to the bottom, near the center of the glass. The pc that would normally break off is held in by the silicone.

I was wondering...if I was to remove the silicon in the areas effected, and patch an inside glass pc about 4" longer from where ever the current crack is, would this work??
