Playing with Traps

Is it permissible/acceptable to use two 45s or two 90s and a female coupler to route the immediate drain from a small sink towards the back of the wall and then take a vertical drop down to a P-trap? I ask this because I was considering shifting the drain's vertical drop before the trap towards the rear of the sink, rather than directly centered, as a means of recovering some frontal space under the sink rather than having the trap directly in the way. Any issues?

thats basically what they do with the drain on a handicap lav to give leg space under the lav. It turns 90 degrees towards the back wall then another 90 degrees down into the trap.

Sweet, thanks. That was exactly my plan.
