John Venture, Welcome lurker! Very glad you have decided to join fully. There is little I need to tell about the RouterForums
I have looked at other sources (MLCS and Amana) and find no bit with a 2 in (50mm) radius. The 1 1/2 in (37.5 mm) roundover bits have 3 1/2 (87mm) diameters.
I wonder if there is another way to achieve your goal, such as a template that could use a flush trim or pattern bit. The edges might have to be done approximately 100 mm segments and then joined, but it might leave open possibilities for edges individually composed of pieces of differently colored woods.

"Teach your children what we have taught ours, that the earth is our mother. Whatever befalls the earth befalls the sons of the earth. The earth does not belong to man; man belongs to the earth. Man did not weave the web of life; he is merely a strand in it. We do not inherit the earth from our ancestors; we borrow it from our children."

- Wood working, especially router work is too much fun to let "disabilities" get in the way.
