most of the Bourbon crowns
Savoy
the Habsburg Netherlands had one IOTL - Milan and Mantua were too close to Vienna, Tuscany was too quiet, the rest of the Habsburg lands are debatable.
If the third partitions of Poland can be avoided, Poland.
Sweden almost had one IOTL
Britain has the problem that it had its middle class revolution twice already in the 17th century.
The problem with these is that these states are too weak on thier own so the reaction would crush them, only France had the necessary power to resist the counter-attack by counter-revolutionary powers.

Do you mean revolution against a Tyrannic king and a reactionary nobility ending in some kind of bourgeois rule (Republic or Constitutional Monarchy), or do you include all those funny Revolutionary French Dictatorships and that amusing Bonaparte?
