One way of getting 2 line separators in a window is by opening a custom window then use /aline to add all the lines you want to it (/aline doesn't have the line separator limitation like /echo does). After all lines are added you can then use /filter -ws @win . (the . can be any non-null text as long as it exists as the outfile parameter) to transfer the lines to the Status Window

The other method is of course to add some extra characters to the line, /echo -s - where  is just a control character, chr 15 in this example
