The William Optic 2" diagonal comes with a 1.25" adapter, so all the Meade EP's will indeed work. Another nice thing about the WO is that is holds the EP's in place by means of a compression ring, so, as is the case with most diagonals, there is no screw pushing into the EP and making a mark. It is also much more secure.

As a f9.3 scope, compared to the AR-6 which is f8, there is not as much chromatic abberation. In fact I've never been bothered by any. However as a certified Lunatic(tongue in cheek)you may run into some. As a certified filter nut I would suggest you check out the Baader Neodymium Contrast Filter. It does a much better job at removing the chromatic effect in refractors and does wonders for contrast. Much better than the popular minus-violet filters out there. It is also much less expensive. As there is a bolt from the focuser blocking the use of 2" filters screwed directly into the diagonal, you would want a 1.25":
