Looks like the 3-week break has no effect on how far-reaching these Rum theories run. Bet you guys have too much fun of this as well. I'd like to share my template based on K.O.R.N's post so feel free to use it for for your convenience.

Rum has one eye. Eye = I. Rumi is Rum with an I.
As for the W in Wakasa, W=double. Hence Rum(i)'s also a double agent.
You may throw your shoes at me now.
I think it's cute, like "the phone, the sea and I".

I take it that we don't hold the same view about the importance of Gin's question at the end of File 434.
Keep in mind that Gin and Vodka paid attention to 'Shinichi' at that time was because they were responsible for killing him using APTX the poison in the past. When Vermouth devised a plan to assassinate the movie director, Gin must have figured out that it came from her own personal interest, rather than from the usual BO's interest, by these details : 1.She forced somebody to kill the director 2.She didn't oversee the event but let Vodka do that 3.The target didn't seem to be a political figure worthy of BO's attention. We can safely believe that Gin knew Vermouth dragged Calvados with her to hunt down Sherry, fought the FBI and had to withdraw, and that he knew the assassination was just a cover to have
someone's attention drawn away. Because the only funny thing happened in that Halloween costume party was a participator using a double-layered disguise and for some reason one layer was
someone who should have died, Gin asked Vermouth to make sure if they thought of the same person.
Now in the present, even if a BO member doesn't have any prior knowledge or encounter with this 'Shinichi' guy, he would still question the detective's reappearance based on these things:
- Calvados died on the same night that 'Shinichi' appeared, and Vermouth clashed with the FBI despite her carefully crafted plan.
- In the list of APTX 4869's victims, the names "Shinichi" and "Haneda Kouji" are placed within one's view, and both are confirmed dead.
Should that attentive BO member using Gin's logic mentioned above be Rum or Bourbon, then the chance that they discover 'Shinichi' isn't dead is very high.

Don't forget that in File 895 Bourbon mentioned Gin's style of dealing with the Pisco case, proving he could gather enough available data from those past BO missions, which in turn indicated some kind of archive inside BO for storing information. Their latest interference with the ASACA-false alarm case is another sign supporting this. On the other hand, I was impressed that Bourbon conducted a thorough investigation of Sherry while doing Scar Akai's disguise. Multi-tasking at its finest.
You may as well consider the option that their conclusion would be 'Shinichi is working with the FBI which explains why he goes missing'. In the past that was wrong but now it's as real as it can get. So, wouldn't you agree that Kyoto event is a perfect fit for a game-changing move ?

Well, currently there are 2 red flags regarding Rumi :
1.
Why did Rumi ask Conan's group for help during her debut case ? At that time they were in the middle of lunch time, not recess or after-class; all the students were presented in the classroom but she deliberately approached the Detective Boys (for no particular reason?) and later gave them hints "by accident", suggesting she knew Conan or the group could solve the code/murder - something that not even Gin or Bourbon could know that beforehand.
2. Why did Haibara get a similar "BO aura" from Rumi, yet still decide to trust her ? Even if Haibara can relax temporarily now that most of BO members think she's dead, a skeptical person like her would still be in doubt of Rumi. Oddly enough she trusts her instinct so much that she denies assumptions from Conan who has utmost trust from her.
I like Rumi though, so I don't care if she turns out to be Rum (which is unlikely imo). For Kuroda, I see no red flag for him at the moment, and in Wakita case, can't say because of his lack of screentime. That said, Rum's identity is not one of my top priorities. I don't have enough concrete clues to guarantee a legitimate answer, and I don't do wild guesses. So I'm just gonna take it easy from here, enjoy the ShinRan canon (especially Conan being lovey-dovey/an eyesore to everyone from now on) and channel my energy towards Gosho to confirm my other ships.
