I once had an idea for two songs I thought would go really well together, me singing one while my daughter sang the other. She, who actually knows something about music, pointed out that one of the songs was in 3/4, the other, 4/4. But we did it anyway - I think we stretched the 3/4 into 4/4 to make it work.

I felt that, to paraphrase a quote from the war in Vietnam, we had to destroy that song in order to sing it.
