None of these three are known to work reliably.  You could probably get some 
of these combinations via an interstem of something highly compatible like 
Marianna.  This spring I grafted asian pears onto quince with a 
quince-compatible interstem and found it only added about a minute to the 
time it took to do a graft (thanks for the idea Lucky).

Euro on American has been used a lot, but in rare cases it shows delayed 
incompatibility.  Myroloban will work for both asian and euro as will 
Marianna.
