Having a 150x1800 Mak on that I utterly love (also on an HEQ5Pro mount) I'm obviously biased, but I think you need to consider this:
If you want to get your feet wet with imaging consider a shorter focal length scope like an ED80. Long focal lengths add demands and complexity and may not be the easiest rig to start out on. Big unwieldy tubes like a 120/1000 refractor are hard to tame beasts, too.
If you're not worried about imaging, the 6" Mak will perfectly complement your big Dob, and likely replace your 8" Newt. I haven't got a big Dob, but between my 6" Mak and my 8" Dob the Mak gets almost 100% of the observing time. The Mak is just so much more pleasant to use and look through, despite the effort of setting up the EQ mount every time I want to use it. I'm only keeping the Dob because there is little gain in selling it. Now, I should mention that I'm mostly interested in narrow-field stuff. However, with your big Dob you've got the wide field covered anyway.
Cheers
