Installing two sconces on existing light switch

I want to add two wall sconces on either side of a passageway, using an existing spot where a thermostat for baseboards (now gone) is cut into the wall for one light box, run the wiring over the top of the wall (not floor-to-ceiling) of cabinets to the other side of the pass-through, cut new hole for second sconce, wire it, then run electrical lines to a light switch that's one stud over and presently only turns receptacles on and off. Plan to do it from end-to-beginning (start with last sconce, end at switch). Any immediate red flags come to mind?

Yes, a few red flags.
1) You don't mean you want to run cable up and over on outside of wall do you?
This is a no go.
2) The light switch. Many people look at a light switch, see a black and white wire, and think a hot and neutral is available to tap off of. Not always the case. If you only have 1 cable there, 1 black and 1 white wire, This is a switch loop and power cannot be tapped there.

There are ways to safely run wire on the surface of the wall. Post back and someone can help you. You need special wires and flat wire channels with special fittings.

I forgot to mention tapping into receptacles may be a no go also.
Others will have advice for you.

The wire would run inside the wall, but would exit at top and run across the top of the cabinet arch stretching over the passageway (I was planning to run it through conduit); it's wall with built-in cabinets separating the kitchen from the main room where the sconces would be, about eight feet high, so the only place the (shielded) wire would be "exposed" would be a three-foot span along the top of the cabinet, then back into the wall and down to next sconce. Haven't pulled the switch to check it, though...
