Is there a way to make a shell become interactive in the middle of a script?

I'd like to do something like:

do lots of stuff to prepare a good environement
become_interactive
#wait for Ctrl-D
automatically clean up

Is it possible with bash? If not, do you see another way of doing the same thing?

Structure it like this:

test.sh 

#!/bin/sh
exec bash --rcfile environ.sh

environ.sh 

cleanup() {
    echo "Cleaning up"
}
trap cleanup EXIT
echo "Initializing"
PS1='>> '

In action:

~$ ./test.sh 
Initializing
>> exit
Cleaning up

You can invoke another shell in the middle of the script, but changes to e.g. environment variables would not be reflected outside of it.
