You could. Some ant nests ship large with little slider doors to open more room as they grow. Some with cork plugs they can chew past as they want. Depending on the ant being kept of course. Thing about using sand/dirt is it gives the ants material to work with. They could cover the glass with dirt over time if they wanted.
Generally it is best to plan to upgrade nest sizes as they grow rather than give them a lot all at once to grow into. Most nests on the market have a two+ port setup so you can add on to them as you go. Attaching a new nest to the old one with a little bit of tube each time they need more space.
As far as top down vs side view, it really depends on the ants. Some ants need to hang from the ceiling, others don't. Some ants are more light sensitive than others, and side view nests are generally darker/more shaded than top down.
I only know about my own ants, Pogonomyrmex Occidentalis, so could not advise specifically on yours. Except about the dirt of course, any ants might use provided dirt to cover your view into their nest.
