To increase the area of the cap which is supported rather than leave the middle unsuported.
I can understand that with you version you have designed it so that the original caps do not have to be touched, making it 'bolt on'.
The design of the other girdle which uses machined main caps has been proven to work and has been in used for several years with many championship winning YB engines.
