1250' is only 1100' above the runway elevation... or even 900' above the DA. Most jets at MLW rather than MTOW would be able to do that! (7nm to climb 900'...)
In the event of having an engine out and being unable to clear terrain using the published missed approach then I would expect your ops department to either publish an engine out missed approach procedure OR restrict the weight that you can land on this runway at.
