I'm not saying the bullpen is good, just that it has only given up one lead all season. Certainly gets rocked in lower leverage situations. The problem in my mind, is that Oliveros and Achter are in reality no better (and probably worse) than Graham, Pressly and Tonkin. So that is at best rearranging deck chairs. Perkins, Boyer and Fien aren't going anywhere (yet) and Thompson has certainly earned a little bit of a leash. There is your 7. Duensing is probably cooked, but there is at least a little bit of reason to hold out hope for a second lefty and he isn't killing them yet. In addition the guys mentioned aren't lefties, so really aren't replacements for Duensing anyways. If you want to swap out Thielbar, I'd be fine. Stauffer doesn't need to be replaced by another arm, should be a bat. There is certainly room for an upgrade in the bullpen, but the guys called for aren't really that, at least over the reliever that actually matter.
