X11 - Ability to start a program instead using WSL

For the AIX Server I need the option +byteswappedclients, which is not possible with wsl

I would like to have an option like in winsshterm

to launch an Xserver instead of wsl.

Another solution would be a possiblity to start somethin when xpipe starts. e.g. C:\Program Files\VcXsrv\vcxsrv.exe -multiwindow -clipboard -multiwindow -wgl +byteswappedclients
