The First Republic is very badly served in alternate history generally. If the Revolution happens at all, it tends to fail earlier, or bloodier, or end up in a much more successful Bourbon Restoration. Napoleonic timelines fare a little better, though they tend to fall in to either hagiography or The Corsican Ogre (when, of course, his worst and most unforgivable crimes were in Haiti- crimes merrily supported by Britain, Spain and America.)
Napoleon is also treated as an inevitable ruler or leader of a failed coup d'etat. His prominence was incredibly unlikely (even assuming he survived his brushes with death through the 1790s, there were something like a dozen other generals approached to lead Brumaire!) but it also assumes that the only outcome for the French Revolution was a crown, or Cromwell, or both.
I would really love to see a good timeline about a Republican victory, ideally with a minimum of fratricide- messy, bloody, still tainted by the Terror, yes, but exploring what France would look like if all those fascinating figures had made it through the decade.
What would feminism look like if des Gouges and Roland and Theriancourt had successfully built a political space for armed women citizens in the greatest power in Europe? What would modern conceptions of race look like if L'Ouverture's Department of Saint-Domingue had drifted uneasily onward as a quasi-satellite republic of the Western Hemisphere, uneasily pretending to be part of France? What about the little nationalisms of Europe, with that fascinating paradox that the French Republic that was quashing its own regional identities was now the great hope of the Irish, the Poles and Jews throughout Europe's ghettos?
I'm not saying a surviving First Republic would be utopian, far from it. But the lazy assumption that it had to fail, and/or had to be a bloody hellscape is a cliche that should have lost popularity when the Scarlet Pimpernel did.
