I have a room where all the wall outlets are half switched, bottom half always hot, top half are run by two 3-way switches. One of the 3-way switches is on a wall I am removing and turning into a pony wall. Instead of just wiring it together and hiding it in a junction box can I convert one of those switches and turn it into a wall outlet while retaining the ability of the other switch to switch the half outlets? The switch I want to convert is not the one that receives power, it's at the end of the line. It is a 3 + ground wire.
The 3 way switch that I'm leaving that is the start of the line with power coming in has black bottom right, red bottom left and black top left. Inside that box a red and white are connected with a wire nuts.
The wall plugs are all snipped on power side with red on top, black on bottom and both whites connected.
