No I haven't considered it really has it's not a problem and it works fine. Thats was the point in mentioning it because if it works ok in this orientation then it will work fine in the other and to be honest for this size machine it's non starter to have gantry run Vertical.!

Agree thou if space was limited and it had to be vertical then it would make sense to design a counter balance into the design from the start just to help the motor out a bit.
