Unfortunately, no.  outside-staff-padding does not have a specific 
default value defined for any type of grob.  This is the main limitation 
of \offset.

Internally, Axis_group_interface::default_outside_staff_padding_ is 
0.46, but \offset has no knowledge of that value.  Instead, it will see 
the grob property as unset and will not be able to perform the desired 
arithmetic.
