No.

There are aftermarket conversions for the -A3A engines that have the
hollow crank shaft.

MT-Propellers has an STC for an electric (3-bladed?) CS prop.

How many knots would be gained with this?

The consensus is little top end would be gained, although a few
additional knots would be possible by allowing the engine to operate
at higher power at lower altitudes.

See this google thread for a discussion on fixed pitch vs. C/S.

Hi Lucky,

Congrats on the license!

Think of a CS propeller as an overdrive. Simply, it's purpose is to lower
the fuel consumption by taking a bigger bite of air in cruise. You basically
get the same cruise speed for less rpms.

Properly used, a CS prop also helps to maximize engine life. Improper or
misuse of a CS prop can render even a new airplane to glider status
quickly,especially turbo equipped aircraft.

There are other benefits and caveats, you will learn them if you go for a
complex endorsement.

HTH,
Marty
