no.

the xkb map is actually kept in the client, in order to do what you propose
you'd have to send mapping notify events with each enter/leave event and let
the client refresh the keymap if necessary. Possible, but then you need to
define what a "window" is.  
the definition of a window in the X protocol is merely a rectangular area on
the screen clients can draw to (disclaimer: details missing). that applies
to virtually every visible item on the screen, though with recent efforts
those sometimes get consolidated into a single window. in short, what a
window is on the client is fairly unpredictable and since windows appear and
disappear all the time, a commandline interface for such a task would be
entertaining but mostly useless.

the definition of "window" you refer to is mostly implemented in the window
manager and doesn't apply here. you really need the WM/DE to do this kind of
stuff.
