I've only heard of this power configuration existing in the german He-177 bomber but never heard of any example in the GA world.
Why hasn't this power configuration gained any popularity?
I can see many advantages to this approach:
And the biggest advantage:
Even when coupled with crappy engine(second-hand snowmobile engine, chinese rotax clone, go cart engine etc.), this configuration might have a higher safety margin than a certified aircraft engine. Two crappy engine quiting at the same time is a very unlikely event - much lower chance than a single engine failure.
How about a two-stroke RV-9 powered by two rotax 583, instead of Lycoming O-320？

I can see many advantages to this approach:
- A PSRU is mandatory for an autoconversion engine or a two-stroke snowmobile anyway. Instead of having a separate PSRU on each engine, why not hook up a single PSRU with two engines? Less weight potentially.
- Bigger prop for higher efficiency when compared to a twin engine configuration
- No asymetric thrust on an engine failure
