Don/Coop Plot Bunny for Adoption

Okay, I'm a huge Don/Billy fan and read every single fic of this pairing that I can find. Now, I don't write, but reading all of these fics has given me an idea that I really would like to see done and I'm hoping that I can inspire one or more of the writers on this comm to turn it into a reality!!!!

Anyway, here's the deal:
The background: Don and Billy were together during their time in Fugitive Recovery but than something came up and thus Don took the position in New Mexico [perhaps Don felt it wouldn't work out in the long run/Don had the family pressure to be more 'available'/whatever...] but Billy had said that he would always be there if Don needed him. Which is why he showed up when David, a member of Don's team, requested a member of Fugitive Recovery in Man Hunt.

The actual story: spending time with Coop again makes Don revaluate his earlier choice and decides that he doesn't get it anymore/decides that it wasn't worth it/decides that it is no longer valid and he really asks Billy to stay with him [ie, not like he did at the end of Man Hunt] and Billy accepts.
Now we all saw how Alan really didn't like Coop during the episode and I want to see him as well as Charlie having to come to terms with the new situation. Especially because Don, in typical Don Eppes fashion, never told the two of them that he's bi, much less ever had a serious boyfriend. I guess he'd try to break that news to them first [over dinner? a night at home?] before telling them about Billy and how he's staying and moving in with Don, but that quickly comes out too.
As far as Alan is concerned, I would expect him to be against it pretty adamently at first until he starts to see just how good Coop actually is for Don. Perhaps he sees Don's more relaxed/smiles & laughs more... or he sees Don being able to finally break down as he trusts Billy so much [if so, I'd expect Alan to be somewhere where he's no expected and Don and Coop think they're alone or Don would never show such weakness]. Basically Alan doesn't 'accept' the relationship until he gets real proof of how good it really is for his eldest and then he's forced to realize that it really is what Don needs despite his wishes and dreams for him.
I guess Charlie would also have to come to terms with all this new information on his brother [I don't see him as being bi or gay too in this fic, for the simple reason that it is... uh... statistically unlikely that they've both been hidding the same secret not to mention the fact that it would increase the angst factor if Charlie has to struggle to come to terms with this unexpected side to his big brother and the fact that Don keeps so many secrets from his family when he (Charlie) doesn't do the same].

Hmm... can you tell that ideas spring quite quickly and elaborately in my mind? It's very easy for me to come up with them but I can't for the life of me write them!!!!!
