I can see how that can be a problem with truly difficult terrain (places like Queenstown, NZ, and I'm sure there are worse) but normally if you are on the SID and off the EO procedure you would be able to turn back toward the runway and then follow the EO procedure or just fly a safety heading from there.
We have one where the SID takes us towards rising terrain and I just brief if we've commenced the SID turn and suffer a failure, we will continue turning back over the airfield and fly the EO heading from there.
We have another one where the EO procedure caters for failures at various points along the SID.
