I'm no mechanical engineer, so take it with a heaping load of salt, but if a configurable system with as many constraints already imposed by the number of gears and derailleur system is discussed, and no super small cogs (say, below 13t) are necessary, why not mount said cogs to a single carrier directly via a clever mechanism -- maybe take a page out of e*thirteen's two-part cassette design.
Obviously has the drawback of being incompatible with other cassettes etc, but how likely is it you were going to swap all that much anyway?
