It should be possible, unless there are more snow storms. Note all the comments about Rockslides - not everyone can boulder with a backpack unscathed. Note also that the milepost on the road is not V9, but V7 - I believe that changed in the past few years. Many trip reports say V9 but there is a gate and a road that you follow up to the rockslide, at V7. There is no trail from V9.
You won't be alone up there. I've only day hiked those trails, simply because it gets pretty busy at the major attractions like the falls, and I prefer more isolated areas for backpacking. If it's your first time in Yosemite, staying in the valley and day hiking would allow you to also visit the visitor center and some of the front country attractions. Wandering through the Ahwahnee is pretty interesting.
