My 2c.. The most efficient way to reach a solution is to use the sort of problem solving heuristics from engineering classes in early college.. This is definitely a complex problem.
A table where we list all the alternative solutions (strat types) to strat in the MA, with their flaws/problems on the other side (i.e. strat types at top, problems on the side, or vice versa). At each box (in the table) that corresponds to a "solution" and "problem", would be listed the possible fixes.
Eventualy you'd have to see one or more patterns that'd best satisfy everyone's idea of fun strat in the MA. It's a clear way to give everyone who looks at it a clear picture of the whole problem, rather than argue some detail or fraction of the problem for a long while, only to see that solving it was in vain because it doesn't fit with any possible/feasible arrangement of the rest of the strat system.
To really harness the whole volume of ideas floating in the players' heads though, there'd need to be some moderating of input to this problem/solution matrix. Otherwise it'd fill up with redundant submissions, random spam, whines, etc.
