Oops, it turns out to remap rightAlt the sequence is

xmodmap -e "clear mod1" ; xmodmap -e "add mod1 = Alt_L Meta_L" ; xmodmap -e 
"keycode 108 = Hyper_R" ; xmodmap -e "add mod3 = Hyper_R"

I assumed keycode 108 is the keycode for right alt, which should
be ok for a modern pc-keyboard.  You can check the keycode number with xev.
