I was thinking about this today. Here's how I'd do it:
The board arrangement would be black in the middle, surrounded by the
colored coasters such that no coaster is adjacent to a coaster of the
same color. Put all the queens (every color from both Xeno and
Rainbow, save either black or white) in a hat and each player draws
their color out and places it on the center square of a coaster not
adjacent to one of their own color (for black or white, this means a
corner coaster). Once everybody has their queen on the board, they
go around the table putting their drone on somebody else's queen
(that someone else hasn't already capped), so long as that queen is
not on their own color. Then once again for the pawns. Now, let the
games begin. The colored ones are trying to get to one of the two
matching coasters (and fighting with another player who's vying for
one of those two as well). Black (or white) only has one matching
coaster, but has the advantage that the starting configuration favors
black as the most accessible coaster.
Thoughts?
