Line-Line voltage derivation from Line-Neutral voltage using ADE7758

I am using ADE 7758 in wye configuration & reading the Line to neutral voltages. Is there a way of getting Line to line voltage from the same readings?

My hardware is fixed. Hence I cannot change the configuration. I tried calculating (Vrn+Vyn)Sin60 = Vry.  This works fine as long as all phases are balanced. if unbalance is >40V, the calculation fails.  Can you please suggest a work around?
