Making the stand taller shouldn't be a problem. 34" shouldn't pose any problem if you want to make it that tall. As long as you are fine with using a step stool to do a wc, then go for it. I think that anywhere between 30"-36" would provide a nice viewing angle.
You can always make the stand a little wider than the tank. The main thing is to make sure that the back wall of the tank is supported. Instead of making all the upright supports in the corners of the bigger stand, make the uprights and all the framing to fit the tank perfectly. Then just use plywood to make the extra 2" that you need.
