...Has anyone done an engine test run like this?

I almost forgot: A well-known German manufacturer did this at the factory
last year (mighta been 2015), and trashed the new glider and trailer
bound for their USA dealer...

Can't make this stuff up!

I've seen a fuselage-only engine test at Kirchheim

Right, SH was not the manufacturer I mentioned above ;-)
Though I can think of some of their customers who've damaged
their plane/motor trying what the OP suggests...
