You don't need powershell for that.

<file name="/usr/local/bin/runas">
#!/bin/sh
export PS1="% "
cygstart --action=runas mintty --title=Admin -e /bin/bash -il
</file>

The export of PS1 is to mark that the terminal window is in
administrative rights.  You can modify the shell program to dash, ash
zsh or whatever you favorite shell is.  Make sure to issue the
interactive and login support for the shell.
