if by make sense you mean defy evolution completely...then yes it would make sense.
You probably don't know what evolution is, beyond it being a fancy word you read on these forums.
But as amazing as it may seem to you, nocturnal to diurnal evolution (and vice versa) has been shown to happen in many species of primates (and some other creatures too, for that matter).

...we find that the pattern of variation within and among primate groups in eye size, corneal size, retinal morphology, and opsin distribution are all consistent with the idea that there is considerable evolutionary flexibility in the visual system. These results suggest that primate lineages may evolve from diurnal to nocturnal, and vice versa, more readily and more rapidly than has been suggested by the use of strict parsimony models.

...to better understand how the nocturnal owl monkeys developed retinas with many more rod cells than cones, while capuchin monkeys, which are active during the day (diurnal), developed more cone cells than rods.

During their evolutionary history, some species of spiders have changed from a nocturnal to a diurnal lifestyle, and the important change in their environment was irradiation by sunlight. ... The results provide strong support that diurnal spiders are in a more evolved stage than nocturnal spiders, so they secrete silks with an evolved mechanical resistance against UV irradiation.
