Modifying 20 gallon acrylic - need advice

[Techy-Mechy]

I'm currently designing a nano tank that will be made out of a 20 gallon TruVu acrylic tank (24"Lx13"Wx16"H). I plan on dividing the tank by placing a false wall 7" from one end so that the main tank viewing area is approximately 17"Lx13"Wx15"H with a sump/refugium on the back of the tank (I will be viewing the tank from one typical end of the tank). Currently, the top flange is about 4 1/2" along the side of the tank that is typically used as the rear of the tank (has slot for HOB filter, etc.) and about 2" on the typical "front" side of the tank. I want to change the flange so that it is 2" all the way around. Because the typical "rear" of the tank has the HOB filter slot cut out of it, this modification will only leave the 3/4" flang where the slot cut out used to be. I'd like to modify the tank by cutting the flange down to 2" all the way around the tank and glue another 1/4" thick, 2" wide acrylic flange on the top of the tank. Do you think that this modification will be strong enough?

Please respond and thanks,
