Personally I'm not very keen on "loss-based" victory conditions, nor variants that outright take away an intrinsic part of the game (like "no great people").
So I'd rather have a normal VC with a good twist.
Something like
There could be other special victory conditions, not necessarily the ones fixed by the game... for example having all 7 religions in at least 10 cities.
as a side requirement next to a normal VC could work.
Or for instance having a city with at least one of each type of great person settled (including GG).
Or having a truly cosmopolitan city in the sense of requiring to have a city with all available normal buildings in the game (not wonders). With the 7 religions that could include all 3 religious buildings of each of those 7 religions... And of course academy, military academy and Sotland Yard, as well as at least 1 of each type of GP settled, to be truly cosmopolitan.
I don't fancy a space colony much as I find the early game the most interesting and having to rush through it to make sure you have enough time to complete the game is not appealing to me. Similarly with Culture, at one point it's just hitting enter 75 times.
To keep it interesting for the top dogs and in general in order to avoid having to go at least to computers (laboratory) and ecology (recycling centre), the "all buildings"-requirement could be in relation only to the techs researched. So if you have researched combustion for instance you need public transportation, but you don't need to tech further. Basically by end game, the city in question should not have any normal building available for the queue, just units and wonders (of course it could apply to any number of cities, if just 1 city would be deemed too easy).
I would like requiring all religious building though, including the cathedrals (but maybe only for the religions present, no need to spread all first). Likewise with requiring academy, MA and SY. I do fancy the settlement of all type of GPs as well, so as to force people to produce all different kinds (by popping or researching appropiate techs). A philosophical leader might help.
Oh well, just an idea. That's what the thread is for, right?
