hatches

my car is an hhr, so the back hatch opens up. is there any reason why i could not put a hatch to open up in the front of a tear instead of opening in the back?
using the term "tear" as in general. still not sure if i am going for a curve or more flat form.
but was just thinking of using space between both hatches (with out having to unhook tear and turn around. maybe putting tarp over in case of rain of extremely hot, sunny weather.
