Some plants need a specific lighting schedule in order to reproduce (i.e. need exactly 10 hours of darkness without any exposure to light to trigger flowering in some houseplants). However as far as I am aware, there aren't many, if any at all, aquarium plants that need a specific photoperiod to flower.
It could also mess with certain fish and their spawning if you have some that are sensitive to photoperiod as well. I know that rainbow trout can trigger early spawning if they are exposed to accelerated photoperiods (like in hatcheries), and ultimately decrease their reproductive cycle by 3-6 months.
I would look into the types of plants and fish that you have / want to get and see if they are affected by weird photoperiods before going with it.
