Xavier Paul has played CF at the MLB level. I'm assuming his defense is below both Stubbs and Heisey, but perhaps he would be adequate for part of a 1 yr. stop-gap. Stubbs could play against LH starters, and Heisey could be the backup plan (or supplant Stubbs altogether).
I got thinking about this when I looked at some stats of Victorino and saw he didn't do so well against RH pitching. Xavier Paul has shown good results (in an admittedly small sample size) against RH pitching.
