This would need the Earth to make one complete rotation around the Sun in an exact whole number of times it rotates around itself. …which is not the case right now and extremely difficult (meaning near impossible) to change.
…no daylight savings…
Okay but now we have a greater problem : we have to change (twice, a year) the time when business, school , stores etc… open and close, for it to be convenient with outside natural light. So, in my opinion, this is not an improvement.
