manual table reorg

I have a table with about 1.2B rows using 230G of disk space. The table is very large , but very narrow (row size is 22 bytes).  I believe that it has 'holes' in it because it is being loaded daily via a MERGE command in append mode so I think that some of the blocks are left empty. I want to reorganize it, but I want to do it manually rather than using oracle's tool. HEre is my plan:

- have application team stop all the activity against the table

- create a new table and copy all the data from the old table to the new

Howdy, Stranger!
