Any pro's or con's on trying to convert a standard alpha to a counter rotating alpha?

I priced it out a year ago and it was quite expensive to convert to c/r. I bought used instead.

I don't believe that it would be economical to convert, there are a lot of parts that are different, it would probably be cheaper to buy a counter rotater and then sell one of your right hand drives.
Just my $.02

That's what I was thinking
