Probably not. If those included EPs are anything like the ones that came with my NatGeo Aldi dobette, they are utter junk. You will need an actual
eyepiece for this exercise. A plossl or wider, and maybe about 15x of power. Not sure about the focal length of your newt, but I suspect none of the eyepieces you have for the other scope would work. The 32mm would be the most likely candidate, except the newt probably won't accept 2". With the gear you have, the 32mm in the 10" is your best bet I think. Failing that, a pair of 10x50s if you have access to one. Some finder scopes can work well too. Reasonably dark skies are mandatory if you want so see more than the core, regardless of what you use.
One or two darker features of M31 you can probably tease out more easily with the dob, but to me it's the overall appearance that makes this object special. And low power is the way to go for that.
