This all works rather well (depending on what you mean by "dynamically").
gdb developers do it regularly. :-)
bash$ cd $build/gdb
bash$ gdb gdb
[...]
(top-gdb) r -nx hello
[...]
(gdb) r
Starting program: /home/dje/hello
Hello.
[Inferior 1 (process 9905) exited normally]
(gdb) i
(top-gdb) c
(gdb) quit
(top-gdb) quit
bash$
Do you have something specific that is not working?
Note that above I show how to get back to top-gdb from the child gdb
without terminating the child gdb using "i" or "info" without
arguments. See gdb-gdb.gdb for how this is done.
