DIYbanter - Fake fence post corner?

I have an issue with a street light wire weaving in and out of my property
line. I was able to dig one hole about as safely as I could near the front of
the house. I need to bring it up a little further but then it will lead into
the wire coming in on an angle. I am already working around this wire and
sitting in almost 2ft into my property. If I put another post at angle, and
instead of putting the fence panel on angle, build it out to 90 degree as
normal and put a stabilizer post maybe either on top of a few inches of tamped
gravel, or on top of a deck concrete block buried into the ground a little. OR
just sit it into the dirt tamped a little and do nothing else with it other
than use it to keep the fence from sagging in that little area, if that would
even be a problem. The distance would probably be 3ft to the other angled post.

Same thing for the utility boxes in the back. I was going to box around them
to keep them outside but there are so many wires and that stupid street light
wire comes in on an angle there.. So if I fake the corner post on that one
too.. I figure the load from the wind would push on to the connecting posts..
I have drawn pictures to show an example..
