As always, tasty playing, chas...
I really think you owe it to yourself to check out the BK-9, chas. While it may not QUITE stand up against the KeyB or C2 Nord, the Hammond sim in the BK-9 is VERY close (FAR better than the sim in the G70), and would allow you to have basically all of your needed tools in the one keyboard. The drums are a considerable improvement over the BK-7m (I have both, so I know!) the chord sequencer makes laying down a quick head or vamp a snap, and still allows you to easily do Variation and fills, etc., and the audio loops section would easily allow you to use audio brush loops and real jazz drumming...
Not to mention, the SN jazz guitar patch is almost prescient at figuring out how to 'guitarize' your playing.
See if there's a store up in the ATL that has one...
