can one invoke the tclkit embedded within a starpack?

Assume that a person has managed to create a starpack, containing a
merge of a tclkit and application T. Also assume that part of T
embedded into the starpack is the code for a second, independant Tcl
application - Y.

Is there a way, from within application T, to make calls to the
embedded tclkit  so that one would get results that were equivalant to
saying

exec tclkit Y y-args


And no, this isn't MY design. Someone on another list was asking if
they had to embed a second tclkit into the starpack to be able to do
this...
