This is a REALLY GREAT IDEA - one of the best and simplest tweaks I have ever made. I tried the Audioquest jumpers and they were an improvement over the stock bars, but some custom made silver wire jumpers I am using now are just the cats meow. To test effect without spending money, just replace the stock bars with one of your pairs of interconnects and see if you hear any difference. I think you will.
Here are some commercial choices:

Most special order interconnect makers will gladly make you a really short set of interconnects.
Or, make your own out of a little bit of silver wire and some quality RCA jacks. Its easy since you only need one lead to the pin on each end.
