I've made that exact clone before and it turned out great, very close close to the actual Ruination. An oaked version does seem intriguing but not sure how it would turn out. To me oaked beers taste better in darker maltier ones than in lighter ones like the Ruination. Which is why i think the Oaked Arrogant Bastard is such a great beer. The oak compliments the dark malt flavor and vice versa.
On the yeast i have no idea since i have never used a lambic yeast.
But have at it, and let us know how it turns out.
I believe Homer Simpson said it best "Alcohol, the cause of and solution to all of life's problems"
