i would, but i guess my next adventurer has just been blessed by armok himself, see for yourself:
i just followed the directions in earwig thread, do as follows:
copy the large or medium iland parameters and edit them as follows:
maxelevation 20 or something similar
minimum mountain peaks 0
minimum volcanoes 1
and minimum rivers 0 to cut down on rejects (null all the other rejection parameters too, including require playable civ)
you will probably still get around 200 rejects and need to allow all rejects, but it will go really quick and history will gen to 1050 in like a minute or so (did for me at least)
edit: aww too bad speed dropped to normal levels after my first move, oh well ^^, still kinda strange
edit2:ok here are the worldgen parameters i used:
