Single to double vanity drain/vent ideas?

[dadamw8]

Long time lurker, first time poster! I'm looking for the easiest and best way to make this single lav waste/vent setup into a double. The current trap adapter is in the center of the wall and the new vanity setup will have an 18" drawer base cabinet in the center and a 30" sink base on both sides of that. Which would make my trap adapters need to come out right around where the two visible studs are at in the corners of my wall and picture (16" off corners roughly). I can handle cutting and heading off the framing and running the pex but I'm unsure about the best way to plumb the new double lav drains and vent. I'm in VA as far as codes go. Thanks for the help!!
