If possible, lambda/kw should become a synonym of lambda (and the

I am strongly opposed to that.  Lambda is primitive syntax and deeply hardwired into most Schemes.  We should not ask implementers to change it.  We added caselambda rather than attempting to integrate multiple bodies into lambda.  (Of course the implementation of lambda/kw may expand into lambda on some systems.)

The same should apply for other extensions.   In particular, I think that as a matter of policy we should have keywords *or* optional arguments in any one procedure definition, not both.
