Oh, I'd heard the thing about Shinn, but I hadn't heard that the reason Cagalli was treated so crappily in Destiny was because Shindou Naomi approached her. Jeez.
But no, Morosawa is not the GS/D writer associated with Geass--it's a different one entirely (I forget which one). So I wouldn't worry about that sort of behind-the-scenes wankery.
(Fun fact: Tanaka Rie, Lacus's seiyuu, and Morosawa are both huuuuge, obsessive Athrun fangirls. Tanaka Rie was always pissed off that Lacus ended up with Kira instead of Athrun. So there's a rumor that Meer was created to give Tanaka Rie a chance to briefly be with Athrun.)
