Forgot about contacting Riku; it makes sense, although:
Lot of baseless speculation, but imaginable, I think.
Rather than being just a coincidence that Sora was the next best choice, Mickey's message could have found Sora through Riku's heart, since Riku is Sora's Dream Eater (really doubt this could have been conceived as far back as KH1, but the next part makes me think they might still play with the idea in the future). As his DE, Riku would subconsciously protect Sora by giving him the Kingdom Key, as an extension of his support (I seem to be stuck on that idea as of late).
XH's heart (or technically XH himself) couldn't have influenced Riku's heart until the end of the storm night, though. After XH expelled Riku's heart from his body, Mickey was able to contact him in the RoD, given that Riku's heart wasn't clouded by darkness anymore (as it was in the beginning of the game).
Since the conversation between Mickey and Sora reminds me more of the one between Ven and Sora in BBS (the beginning though, since Sora not being present on Ven's panel is a crucial detail), it reminds me more of a distant conversation between hearts (not themselves, given Baby Sora's unfitting dialect). Maybe Mickey would have met Riku personally in his Awakening so that he could summon a keyblade, but things obviously didn't work out, so his "message" would have to do the extra work of finding someone else, and therefore not be so personal.That being said it does seem that it can be done by people other than Keyblade Masters, as Riku and Ansem SoD are also conversing mentally during CoM and Terra does call out to Aqua once in the Final Episode of BBS.

I think I could challenge this.And what Gram said too, I also remember it was somewhere said that Mickey was steadily trying to contact the new Keyblade Wielder and was actually reaching out to Riku, but due to his heart being clouded by Darkness, he could only "move down the list as the Keyblade did" if we speak with Young Xehanort's words.

Yeah but a part of Ansem was in Riku's heart so they could communicate through that. Terra also had Master Xehanort's heart inside of him so the "master" side of him could contact Aqua.
