Some things of the API have to change, because e.g. within the context,
you would not call anymore $this->controller... but
tx_registry::retrieve('ctrl')...
Additionally you would not say:
$obj = tx_div::makeInstance($this->contextClassName);
$object->controller($this);
The second line would be removed completely.

Actually I'm not so deep in lib/div as I like to be, but if I understand
it right, the paramters and the configurations object are "global"
objects, and if this is true I would say *YES*, they can be registered
with tx_registry::register($extKey . 'param') and
tx_registry::register($extKey . 'conf') for example.
But then, there is no need anymore to bind these objects to the
controller -> API change.

As mentioned above, I need more code insight and practial experience to
answer this question accurate, my framework only uses one controller at
a time. But here a suggestion (don't know if it is possible): If the
configuration-object is globally available, and if I can see through the
actual configuration, at which place I am, the configuration-objects can
be traversed to retrieve the right controller. Then, we only need to
define a rule, with which unique name each controller will register.

P.S.: I can provide the code for a simple registry-object, but it is
PHP5 only.
