Yes, sounds like a good idea, makes going home more of a positive experience (and gradually something to look forward to?). When you go shopping maybe get some "special" things for the next time you come in e.g. scented candles, some aromatherapy oils to burn, chocolate or ice cream (??), bubble bath.
And when you go out make sure you find time before you go to route out some things you feel content/comfortable/familiar with to leave right there for when you come in e.g. a favorite D.V.D, C.D's, book. Or photo's special to you which you can frame if you haven't already??
Maybe preplan/line up things you want to do, so as less "nothing" time.
Is there anything you could treat yourself to as well e.g. something comforting like a new dressing gown, bedding or something really "you" you could buy for your place. Something that really makes "home" feel like home.
And just another thought, if you're used to leaving some jobs/tasks around the home until you come in e.g. ironing/cleaning then maybe just that extra effort to do them before you go out?? That way it's not going to be as much thinking as you get in "I've really got to....". You can just relax and some quality "me time"??
