Recall the cracking issues around the lightening holes in the Lyc crank prop flanges when those cranks were used in hard acro. A prop extension will only make that tendency worse. While I'm sure nobody is actually going to do hard acro in an RV, a heavy CS prop on the end of an extension might cause cracking over time with 'light' acro, whatever that is.
