Put the wider lens on the K-7 and the longer lens which needs faster speeds on the K-5 bumped up a little ISO wise. Now off to get me a Wabbit, oh I mean a K-7. Dave
I owned a K20D and a K10D. When I bought my first K-5 I intended to use the K20D as a 2nd body.
I found the difference in bodies far too confusing when quickly trying to grab a shot.
So even if the K20D might have better ISO performance than a k-7, I think you might be better getting a K-7 as a 2nd body.
I opted to buy a 2nd K-5 as I love the much better Image Quality of the K-5. I'm not rich, I had to sell a load of stuff to fund it.
