The FAA's own research shows that slower stall speeds don't seem to result in increased survivability rates in emergency forced landings in aircraft weighing less than 6000 lbs:

[Docket No. 23746; Amendment No. 23-44]
RIN 2120-AD48
Airworthiness Standards; Small Airplanes With Stall Speed Greater Than 61 Knots

The Small Aircraft Stall Speed Study Group reviewed data consisting of 37,530 reports for the 6-year period from 1976 to 1981, which revealed the following: Emergency forced landings accounted for 14.7 percent of all accidents, representing 16.6 percent of single-engine airplane accidents and 7.2 percent of multiengine airplane accidents. Fatalities resulted from 2.6 percent of controlled emergency forced landings and 17 percent of uncontrolled emergency forced landings. For single-engine airplanes, these values were 2.1 percent and 13.4 percent, respectively, while for multiengine airplanes, these percentages were 8.5 and 34.2 percent, respectively. Therefore, the chances for a fatal emergency forced landing are much higher for a multiengine airplane than for a single-engine airplane. However, a single-engine airplane is twice as likely to have an emergency forced landing as a multiengine airplane. Overall, the percentage of fatal emergency landing accidents where the pilot retained control until the crash was 2.7 percent for single-engine airplanes and 3.5 percent for multiengine airplanes.
One multiengine airplane with the highest stall speed of 76 knots had the lowest survivability ratio (one minus the number of fatalities/number of accidents), of 84 percent. This value matched the survivability ratio of a single-engine airplane whose stall speed was 55 knots. There were two multiengine airplanes that had 100 percent survivability; one had a stall speed of 60 knots, the other had a stall speed of 74 knots. Furthermore, survivability values for multiengine airplanes above 70 knots did not appear different from values for airplanes below 60 knots. Statistical data like these resulted in two conclusions. Survivability of controlled emergency forced landings is not dependent upon landing stall speed and a clear correlation between safety and landing stall speed cannot be found.
