Weekly Challenge #22 - Korolev Cross

Korolev Cross design challenge!

We've seen you add more boosters, but how well can you subtract more boosters?

Primary: Stylishly decouple at least four radial boosters simultaneously from an orbit-bound rocket. Keyword stylish. We want pretty pictures.

Secondary: Stylishly decouple at least six radial boosters split across at least two stages (fuel crossfeed encouraged)

Jeb: Yo, we heard Jeb likes decoupling boosters, so we need you to decouple boosters from your decoupled boosters so you can stage while you stage.

Val: Perform any of the above while launching from a celestial body other than Kerbin.
