Why so? Static configurations are one of the easiest.

 /etc/systemd/system/getty.target.wants/getty at tty4.service -> getty at .service
 /etc/systemd/system/somethingelse/xorg at tty1.service -> myxorg at .service
 etc.

myxorg.service:
[Unit]
BindTo=dev-%i.device
[Service]
ExecStart=myX %I

/usr/bin/myX:
tty="$1"; shift;
exec X vt${tty#tty} "$@"
