do I really need to do it as you say? it looks labor intensive
if I dont have a choice, will do it
Well, FWIW, I reckon yr plan is just fine and the other like using a sledgehammer to crack a walnut. Once the holes are keyed and the plugs epoxied in place with some overlapping mat cover there are simply no forces either willing or sufficient to dislodge them. They are there forever.
But I would suggest keeping the half inch inlet where it is (with a seacock with removable handle) and filling just the outlet. Then when you weary of the compost notion, simply install the outlet where is should be up nearer the waterline.
