If your existing light has a "Built in sensor" how can you "tap into it" if its built in? By most accounts anything that is built in is just that, integral to what it is built into leaving no other option.
You would be better off with your 2nd suggestion of removing your existing light and installing a stand alone sensor and a standalone light as well as the lights you wish to install in the eves.
Most standalone sensors will do just what you want, there are lots available, but some consider aesthetics important so I will leave the choice of sensor to you. (They are available from all good electrical outlets and some DIY stores.)
