Every body points out every thing...!! I suggest you shouldn't have been on that SID.If the SE cceiling is lower than the MEA in that cas the route cannot be planned.
SID's may or may not have minimum climb gradients.It is required to be assured that in the case of the most critical engine failing the same can be adhered to if not then reduce the weight if that doesn't help you cannot be using that SID.Similarly a Miss App may have minimum gradients as well
More than airman ship its planning
