OK I finally have the solution to the original question and thanks to all for your assistance!
Found this great clip
MA-002 • Larry Carlton Interview Masterclass Now Larry talks about treating the Valt in this case a G13b9 (great chord) as a G#dim7 and therefore allowing Minor 3rd shifts (E G Bb Dd triads) I also tend to treat Galt (say G7b13) as an Aug triad so I also include G aug B aug and Eb aug. So playing around with all the above I came up with this!
----------------------------------------------------------------
------5-3---------6-8---------8-6-------------9-12-------------
----4-----4-----7-----8-----7-----7-------10-------12----------
--6---------5-8---------9-9---------8-11--------------13-------

--------11-9-------------12----12-----------
-----10------10-------13---------12----resolve--
--12------------11-14-----------------------

This is exactly what I was after!
It fits over a G7 vamp great!
It also fits a D Dorian modal jam, an E Dorian modal jam and just about anywhere else you can throw that dom 7 in (as long as its brought home!)
Resolves to I (in this case Cmaj9 nicely too)
Hope someone else can get use out of it! possibilities are endless!
