Those are fine drawings!
It would work, and be structurally sound.
An advantage would be that if you were careful and if the glass was not tempered (which it probably is not-- usually only the front and bottom panals are tempered) you could cut the end panel down for the other pieces you need.
But I am not sure you want the top open like that.
With the front opening, you will not need it for access. If you are going to have terrestrial fauna, you will need a top anyway to prevent escapes.
And lighting through the glass is not a big problem, there is very minimal loss.
Is UV transmission a goal?
