I'd think it can be done if a competent tech did the work. You're looking at two CATs, and two mufflers plus doubling the sensors (this is where the good tech comes in) plus telling the computer what's what.
If I were doing it, I'd also put a set of headers on. No sense in going to all that effort and expense and only doing half the job.
