I am wondering whether any IEM combines the mid-centric, balanced sound signature of the RE-Zero with the awesome soundstage of the IE8.  Is there anything that comes close?

Hmm, well, I would say that my SM-3 with modded filter comes close to my RE-252 balance, with added warmth (but way less than IE8) and a wide soundstage. But still, they are quite different.

Hmm, the RE-ZERO isn't bad for sound stage, slightly forward maybe but good depth and size.  I don't have a suggestion for you for something that sounds like the RE-ZERO with a wider sound stage.  I'd suggest the Klipsch Custom 3 as an option with a better sound stage that also happens to be well balanced.  The sound stage of the Custom 3 is quite good.

I am also curious about the SE530.  Do these, or any IEMs mentioned above, have a similar sound signature to the RE-ZERO?

RE-Zero with a sound stage close to the IE8 does not exist. The best you can probably do is if you have a good EQ like BBE or rockbox you can change some settings to increase the stage.

Soundstage on IEMs is over-rated, I own both the RE0 and IE8.

I haven't had much success in increasing the soundstage of the RE-Zero by EQ-ing, so I've pumped up the mids on the IE8 instead.  I'm still testing it out, but this is my favorite setup so far.  Here is how I have it set:
 
Lowest bass adjustment setting;
Preamp: -8dB;
 
Hz -- dB
32 -- 0
64 -- 0
125 -- 0
250 -- 0
500 -- +3
1k -- +8
2k -- +8
4k -- +3
8k -- 0
16k -- 0
