Hopefully you don't mind the rather large post. I find it easier to show graphs to tell a story. I don't quite have the accuracy I need at 9-10 kHz on the graph, but all will show comparatively the same so it shouldn't be an issue.
Lets start with the first one - all compared to your preferred FLC8S red/grey/gold
Vs Andromeda - and unfortunately I don't have the Andro here to directly compare (mine was only ever a loaner)
I can't directly compare - but the Andro is pretty close - won't have the mid-range bump you like, but is tonally more accurate, and it does have the sub-bass you like
Vs Dipper - in this case with bass off, mids on and treble off
Similar bass (FCL8S has more sub), but you can always increase the bass with the dipper. A lot more mid-range emphasis with the Dipper - it is coloured in thsi regard, but one of the rasons I love it. Turning the mid switch off changes the shape of the curve but not the amplitude. Personally I prefer the Dipper - but I like emphasised mids. I usually use the Dipper with bass and mids on and treble off. In that config - they are quite balanced, but with lower mid-range a bit recessed
One you haven't considered is the Alclair Curve - here in two configs (one with Comply foam and the other with Shure Olives)
Curve has less bass and is quite a bit flatter - but the mid-range is really good. Might no have the vividness you are after though
Next up is the Earsonics ES3 - flat lower mids and mid-bass, elevated sub-bass, really nice mid-rang and a bit of bump at 7 kHz (Cymbals)
Nothing offensive and a really nice signature which isn't too far away from what you like. personally I like the mid-range a little better on the ES3 (more natural in its tonality)
And last but not least - a really good IEM but on the expensive side of things
64 Audio U10 +G1 module. You can see how close they are. With the U10 you get a very wide stage and extremely good clarity. I've revised my original review score up a notch as tme has gone on, and I am seriously considering asking 64Audio if I can buy the review sample I have .....
Not sure if all of this will confuse matters more or help
