Now it is July 1 and I have responses from kislanko at airmail.net, jlundell at pobox.com 
, Markus Schulze.

Merging is possible, provided each state provides and describes data  
suitable for this purpose, such as:
      Condorcet X*X array.  Because of possibility of extra candidates  
from some states, each state should be required to include data for a  
dummy candidate who gets no votes in that state - such can be included  
for each such extra candidate.
      Plurality data - suitable for both states which do Plurality,  
and for those who use some method not provided for.  For such an X*X  
array is filled out with data as if votes reported had been reported  
for the candidate strictly preferred by each of the state's voters -  
and entered in the X*X array as if voted in Condorcet.
      Approval data - needs thought but my initial thought is as if  
each approval was a plurality vote - does mean a voter approving 2  
gets 2 votes counted but relative counts per candidate comes out ok.
      IRV or Range - examples of methods that should be avoided by  
states willing to have their data included - unless they are willing  
and able to convert to a method that is supported.

Some question merging data from different types of sources - I claim  
it is doable provided the source type is provided for and the data  
properly labelled.

Markus Schulze says to use the Schulze method for cycles - that should  
be considered when agreeing on details.  I would add that there should  
be ONE X*X array for the US for this purpose, so that all cooperating  
states give the same instructions to their electors.
