Another loop that springs to mind is to continue down the valley pass the Mortirolo, then in Tirano turn right and climb the Bernina pass. About 3 kms before the top you can turn right over the Forcola di Livigno, drop down into Livigno itself then do the Eira and Foscagno, before a lovely long descent back down to Bormio.
