I would not use the CODM, because in that case you would need to rewrite the code from scratch. It would be better to copy the ODF file and to modify only the code for the layout components. Of course, you also will need to create all the layout components and to place them in a separate folder. You may ask MDA for the guide for sample set creators to learn how to modify ODF's. It's definitely not going to be a simple job, but if you succeed, I think many people will be interested.
One comment on the layout design: you color-coded the undulating stops (Voce Humana and Unda Maris) as reeds, personally I would find it more convenient to have these stops placed close to their natural companions (Principal 8 and Flute 8/Gemhorn 8/Traveur 8 respectively).
