IMO if you take a little from the canopy and add some to the stand you would be happier. I hate having to lean over to look in the tank. If the tank is more "eye level" it tends to look a little better as a center piece for the house. Also a shorter canopy makes the tank look bigger since the stand will be so large. You want people to focus on the tank and not the "furniture" part of the tank. Also with a sump, refuge, skimmer, reactor... Any combination you decide to use for filtration you would have more room for it all. Just my opinion though and it is your tank after all.
