I went with 6066 camoflauged outpost for 1st choice, simply because Forestmen are cool and I think the set would do well based on that.
Second would be 6080... It's a castle with a good selection of figs. Would be a great stand alone model or MOC fodder...
3rd 6041 Armour shop.... Adds to the flavour of your village, competition for the blacksmiths holed up in the castle... Black sword, but it would be the soft kind.
4th 6060 Tournament... Way better than the KK2 version. Realism, pagentry, a page right out of history. The bardings and female fig add to the desire to see this become a Legend.
5th 6071 River crossing... The female fig (and believe you me I WANT this fig) and more Forestmen. The model itself, good for parts.
So that leaves the battering ram... Not great as a stand alone Legend, but would be neat as part of a Legend line, you know, modularity, realistic designs, believable factions...... Basically start releasing all the old sets over again (yeah right) OR better yet, glean the good points of this old sets and make classic vogue by having a "next generation" System Castle line.
Really tough to choose one single favourite, but there is my opinion.
