run bash command in new shell and stay in new shell after this command executes

You can achieve something similar by abusing the --rcfile option:

bash --rcfile <(echo "export PS1='> ' && ls")

From bash manpage:

–rcfile file

Execute commands from file instead of the system wide initialization file /etc/bash.bashrc and the standard personal initialization file ~/.bashrc if the shell is interactive
