"I know that SATA drives can operate on a SAS controller" - you may know many popular SAS controllers than can run SATA disks but don't make this assumption, there's nothing in the SAS specs that state they should also run SATA disks, they just share a lot of common features (connectors/cabling etc.). Manufacturers can pick and choose to do as they wish.
Now your question - no this won't work, it's the SAS signalling that's different, so no SATA-only controllers won't be able to work with any SAS disks at all. Also again it's an assumption of yours that all near-line drives are SATA with a SAS controller - that's not the case, it's the controller that defines the protocol used. Near-line SAS disks are just disks, there's nothing inherently SATA-oriented about them, they then have a SAS controller attached to them.
Dual-porting is a SAS feature that allows a single disk to have two physical SAS links out of its controller, this is usually used to allow for diverse electrical paths but can be used to connect a single disk to two controllers to better handle hardware failure. It's got nothing to do with SATA at all.
