Yes it'll work as you plan.
To be safe install a check valve between the pump and where you tee in. This will protect the pump from the shoreside pressure. Normally even if the pumps are left ON they won't run, unless the shore pressure is less than the pump pressure.
Don't forget a bilge alarm... If something fails it'll let you know you're sinking.
