that is a very good idea: that section down-ish 58 to Oakridge would make a nice return path. maybe start it all with a ride up OR242 into Sisters, down to Sunriver, pick up the Cascade Lakes route, and then back on 58. Probably at least a two day ride for me.
the tunnel is spooky, but there is a small shoulder, and i've got sufficient lighting. the downhill part, as you mention, also helps.
