Hassan, maybe a question to ask is ...
What is going to be the effect on signal integrity
of an .062" (?) long discontinuity of some magnitude
somewhere along on the trace? Perhaps it may be
insignificant.
It seems as though the equivalent circuit presented is
attempting to model some 3rd order analysis of a via.
I might suggest that in order to do 3rd order analysis,
the assumption that all associated grounds are perfect
and identical may be something to reconsider. On the
other hand, it may be perfectly sufficient for your
purposes.
Unintended assumptions can kill ya every time ...
Just my 2 cents.
