The application I'm currently working on has a count of 187 AsyncCall-
back-classes being used as callback of RPC-functions[1]. So alone the if-
elsif-cascade would take nearly 400 lines inside the onSuccess-method
(and the onFailure-method as well, because I print localized
error-messages as well).

Check it out. Write a GUI, that does repeated calls using callbacks
the regular way and your way and compare the result. But I doubt
that there will be significant differences, especially because we're
talking about something that involves a complete HTTP-request-
response-roundtrip that should way more time than the simple
creation of an instance of a class (assuming that this still happens
inside the Javascript-code being generated by the GWT-compiler).

[1] I used a
find -name '*.java' -print0 | xargs -0 grep -c "new AsyncCall"
to find out.
