Add a separate switch to a 3way circuit
Two separate projects.
First project, converting the single light to two recessed lights. Easy not counting the cutting open of the ceiling and the fishing of wires. Remove the old single light and connect wires from its old wires to the two new lights.
Second project. You need to find out where the power comes in to feed the existing light and its switches. From the power entry point build on a new sub-circuit with the landing light and one regular switch or a three way switch setup. It is possible you will need to remove an existing junction box and replace it with one that is bigger to hold all of the new connections, for example where the original single fixture was.
To use 20 amps where previously there was 15 amps you must make sure all the wires throughout the circuit (perhaps a complete brand new strung circuit) are 12 gauge.
If you string a new circuit for the new light while keeping the old lights on the old circuit, do not tie together the neutrals of the two circuits at boxes for example if switches for both are in the same new 2 gang box you installed. But do tie together all ground wires wherever they come together.
