This is probably not an easy task, as best practice is to have the forms installed locally, then having it in the Org Forms.
As for OWA, that's probably just exchanging some pictures in the filesystem ;)
But I agree with JesesWept2, you should check that with support, because you probably have to revert back to a supported configuration everytime you want to have support from Symantec for this type of configuration.
