Pros and cons to both sides of this issue. While the ST data has some merrit there are plenty of caliper relocation kits that work well when done on both ends of the vehicle. For the most part they are often better served on the rear where it's the only means of working with an oem parking brake caliper.
The bigger issue here is "affordabe". Given the size of the stock rotors to do this correctly the new rotor will need to be about 14.5-15.0"min. This is due to the requiremnt of space between overlapping holes of the old and new mounts. That leads to two additional problems- the costly need for a very custom rotors and the fact that the caliper itself may not match the radius of the new part. There's a limit to fitting "any caliper on any rotor" without contact. The body is contoured for a specific need and while it might take an additional 1/2" without problems, adding more can be a problem.
A two piece rotor set up of this size is going to run $650 or so and the bracktes more money etc. etc. By the time you buy hoses for it and all you'll be well into the $1100-1200 price range by my figuring. You still won't have any rotor width gains for cooling and be limited to what pads you have now.
Not a toally bad deal but it leaves a lot on the table for the value. For the added cost of a true BBK with new calipers, sized properly for the need, comign with hoses and pads it will prove money better spent.
