Possibly, but double-strength would increase their longevity,
considerably. The glass cost, compared to the work involved, isn't a
great place to save, IMHO.

Same deal. Double-strength for smaller tanks, and thicker than that for
10G and up. The thicker glass gives more edge to bond, as well as
resistance to minor bumps. I'm sure the single-strength would hold the
water pressure for 2.5G tanks that you describe. Thinner glass is
reasonable, only if you have the commercial injection-molded tank frames
to protect all the vulnerable edges.
I'm still looking for a small plastic extrusion, shaped sort of like a
question mark rotated 90 degrees ccw, for making rims with a soft inner
lip to hold the cover glass. Another way of describing it would be a "U"
channel that fits the tank glass with a side flange as shelf for the
cover glass. Vinyl would be ideal, or polyethylene.
If a cheap variety could be found, it would be nice for making the
bottoms, too. Inset the bottom glass on it, just like on the better
grade of commercial tanks. It would prevent chips, and put the load in
compression, entirely on the sides, eliminating stress breakage in the
bottom pane if the shelf was slightly uneven.
