The 10" meade tube weighs just short of 13 Kg bare. Most 80mm refractors weigh about 3kg. Add focusers, cameras etc and it could be a close thing. Does the capacity of the EQ6 include the weights to balance? A guide scope is much better then an off axis guider as you can move it around to find a good guide star which is not really possible with the OAG. I use an 80mm apo at F6 as a guidescope with a QHY5 guider (lots of little pixels) and this does a good job even if I leave the LX @F10. Worked when I used the original DSI as well but I mostly use an F6.3 focal reducer to make things a little easier. Your 70mm scope is at about F12 so it should work well as a guide scope with exception of it being longer then the meade tube.
