again - there might not be a worst case. The worst case might be that you loose one generator and a couple buses and avionics like after a direct hit by lightning.
Only getting some hard figures would clarify a bit because (see my previous post) an aircraft is NOT UNPROTECTED ! ! ! Or we would fall out of the sky or loose everything every time we get hit by lightning.
So your worst case might be the scenarios we train for with partial or total com losses - loss of some ADC, EFIS, steering computers.
Will a RAT deploy - chances are YES. Would eventually your APU start? Maybe.
To get your worst case scenario we need to know what a pulse of given strenght would cause. So start up your computers and calculate it. Or ask somebody who knows - but they may not tell you - or they will have to shoot you once told.
