HI Imran,
I assume you do use R20 already. If not please advice.
Yes, things have gotten much simpler with Fields. It is a new generation and I guess we will se a lot of new results and aesthetics on the screens around the world (Big words, I know, but I feel it this way.)
Here is a file that uses the Information of the Vertex Map to scale it. Which means the Visibility option (invisible to be precise can’t be used here), but the scale to -1 does the trick as well. BUT: it allows to scale the clones with a brush, lower values, smaller spheres (clones.)
Scene file (updated!)

Please let me know if there is anything else, I’m happy to look into it.
Cheers
P.S.: YOu might check as well the Scale apart from the Push Apart effector, as an option to quickly fine-tune the results.
