Abstract Profiles of Structural Stability Point to Universal Tendencies, Family-Specific Factors, and Ancient Connections between Languages | PLOS ONE
Uses the World Atlas of Language Structures - WALS Online - Home - to try to find out what language structures are the most and least stable by finding out how much they are conserved in language families.
WALS is very comprehensive, though limited to present-day languages, and it needs to be expanded to past ones and to reconstructed protolanguages.

A curious complication that they note: Languages Evolve in Punctuational Bursts | Science
Linguists speculate that human languages often evolve in rapid or punctuational bursts, sometimes associated with their emergence from other languages, but this phenomenon has never been demonstrated. We used vocabulary data from three of the world's major language groups—Bantu, Indo-European, and Austronesian—to show that 10 to 33% of the overall vocabulary differences among these languages arose from rapid bursts of change associated with language-splitting events. Our findings identify a general tendency for increased rates of linguistic evolution in fledgling languages, perhaps arising from a linguistic founder effect or a desire to establish a distinct social identity.
Back to the first-mentioned paper.
We found that across all language families and datasets, the correlation between path length and number of nodes is very high (range 0.65–0.80, mean = 0.75, sd = 0.046), suggesting that punctuational bursts might explain about 50% of structural change.
