I think you should be aiming for a generic composite device block driver.
Then write a fake MBR block device (or whatever you want to call it).
To use a single partition you create a composite device consisting of the fake
mbr and the raw partition.
A vmware split image file is just a composite of several raw images with a
funny config file.
