Actually had this idea before, and Mosh was very interested in it. So, you might have a tidbit already in the works.
Alternately, it might be interesting (if somewhat hard to work with) to have Shirou summon Caster in the first place. There was actually a doujinshi with this premise... at least somewhat. ^_^
I believe the doujin you are talking about is
Gilgamesh vs Rin. The part where Shirou summons Caster is at the end and is only given a small amount of attention. <_<
Got this idea after rewatching F/SN series on youtube; anyway what if Caster had fainted in front of Shirou's house instead of falling unconscious at the steps Ryuudo Temple and it was Shirou that she fell in love with? Whether or not he still ended up summoning Saber I'll leave to the author.
I've always liked the idea of a Shirou/Caster pairing.
On the idea of Shirou still summoning Saber, it could be worked out. Karen in F/HA was master to both Lancer and Gilgamesh. It would be "tense" when Saber finds out that Caster is with Shirou.
On the other hand, you could go with how the previously mentioned doujin handles the summoning situation or maybe another angle if you like.
Off-topic, I'm wondering how some of F1's and Mosh's F/SN fic ideas are coming along.
Very sweet, Shirou/Caster would be something that I would love to see done, also, I can only imagine the results of the fallout between a jealous Sakura and Caster getting into a catfight.
As for this... I'd imagine this would only happen if Sakura started to lose "control" of her dark side. However, this would mean some "Dark Sakura" and I can only think of one way to express how I feel about her.

I've got something that been picking at my brain. How would Caster react to Shirou's ability
Reality Marble or perhaps her first perception, lack of ability.
Anyway, enough of my innane ramblings. Until, next time.
