I have a 150 gallon tank have been thinking about doing the same with either turning it into a corner tank using the 2 7' glass pains as viewing panels in an L shape configuration 1000+ gallons or just 1 7' pain for one tank front viewing panel around 400-500 gallons could make 2 tanks this way. however the glass pains on this 150 I have are 1/2"-3/4" I haven't taken an exact measurement yet.
But as stated above ether of these options would still be to small for a rtc even at 4' deep and 30" tall. you might could do a tiger shovel nose and a smaller gar with at set up like this.
