Since access is not a problem, you could run wires anywhere you want. In this case, replace the existing switch box with a double. Route supply power to the switch box. From the switch box, send two cables (black, white, bare, one to each fixture). In the switch box, tie all grounds (bare copper) together and to each switch. Tie all whites together. Split the black supply and send one to each switch. From each switch, connect one of the blacks feeding the fixtures. At each of the fixtures, tie black-to-black and white-to-white, and bare copper to the fixture grounding screw.
