The docs do not say it can be done.  You should assume it cannot be done.
If the docs would describe everything that is not possible, you'd need
an extra hard drive :)

Yeah... join the developers team and start coding :)

Alternatively, make use of the existing options:

--x-grid GTM:GST:MTM:MST:LTM:LST:LPR:LFM

LTM:LST defines how much time is between each label.  You could get
> mon wed fri sun tue thu sat
without
>   tue thu sat mon wed fri sun
already if you specified "2" in stead of "1" for LST.

This would need to be: --x-grid HOUR:8:DAY:1:DAY:2:86400:%a
or something alike (from memory, not tested)
