Help needed on two way switching

[craigf]

Please can anyone help with the following question. I have a light on the outside of the rear of my house, the switch is in a bank of 4 in a place where no further access to the rear of the switch is possible. I wish to use this cable and switch to run 4 240v recessed ceiling lights. I would however if possible like to make it two way switching.
Switch 1 will be the one in the bank of 4
Switch 2 will be in another room.
Is this possible or am I dreaming ?
