Apparently I must have missed some information regarding the inability of the above set up working. After re-reading all of the post related to by system build and all the other posts that I could find. Is there a firm consensus that this setup will not work?

1. 568.2 set 24/96 Large Front : DSP rear (18bit 5k speaker) = No sound output from rears.

2. 568.2 set 24/96 Large Front : 24/96 rear (18bit 5k speaker) = No sound output from rears.

3. 568.2 set 24/96 Large Front : 24/96 rear (24bit 5k speaker) = Sound from rears.

Unless otherwise advised it looks like I will have to use 24 bit speakers in the rear also.

Almost there!
