Probably close enough to make it worthwhile. I think Floyd would be a great reliever, might even be a better fit since he can get more swing and misses. He's also been really good the 1st time through the order compared to the 2nd and 3rd. Much more dramatic splits than an average pitcher.
In his career:
1st time through the order OPS+ 83
2nd time OPS+ 97
3rd time OPS+116
