   How big

   and how deep are the piers? It may not really add much to attach the posts if the piers are small.

   What you probably need is a concrete perimeter foundation. You may be able to leave all of the existing structure and simply add the new, along with wood framing to connect the house.

   Talk to the folks at Simpson, that's ALL they do is figure that stuff out.

   Get an Engineer

   Hire an Engineer. 

   The work will most probably require permitting. 

   I doubt that the Building Department of who ever issues the permits, will let you have one for a seismic retrofit, with out having a design sealed by a Professional Engineer.
