I should think bolting another 4x4 to the existing posts would work
OK, esp. if you continue the new post to the existing grade so it
ends up with 18" of soil around it from the new raised bed. I'd
recommend at least 3 bolts - one at top and bottom and one in the
middle - through bolted. You could even drive some rebar into the
soil on the side of the new post and fasten it to the post with those
curved metal fasteners I can't remember the name of right now. You
might also bolt the new post to the horizontal members - am assuming
you'd put it beside the existing one and not in front of it:-) Since
it won't be anchored in concrete, the more anchoring you can do to
the existing structure, the more stable it will be.
If your posts are the typical 8' apart, you might consider digging
one more hole in that hardpan and putting one in the ground in the
middle, set in concrete, and bolting that to the horizontal members
of the existing fence. You'd also need a top horizontal member
spanning the entire distance, I should think.
Trellis, having holes in it, won't offer the same resistance to wind
as a solid fence, but if you have a very windy site, that is a factor
to deal with, considering that a mature vine can add a lot of weight
to its support and act as a sail if the wind hits it right.
An evergreen Clematis would be very nice....armandii? I haven't
grown that one - it's marginally hardy where I am - but have heard it
praised highly by those who can grow it. There are so many great
vines to choose from that you might consider a couple of deciduous
ones along with the evergreen Clematis...didn't you say you need to
cover about six feet in length, or am I dreaming?

Now, see Marge is thinking like me... A raised bed of
18".
trellis:
A trellis is a great idea. After I have just dug out
15 plus holes in this nasty hardpan, I'm not to
excited to dig some more. I could bolt Additional 4x4
on the sides of the buried 4x4 to give it additional
height. But of course, I would have to get it approval
from the Neighborhood Control Board. It should fly. I
would have to think of the wind factor and what loads
would occur on this new design. Its very wind on this
hill. I had my barbecue blown over one day. Can you
say "windy". So, back to my thoughts..... I would
have to consider supports. Maybe good old sturdy
structure would have to do for supporting issue.
Once the 4x4's were in and bolted, I would build the
trellis that would follow the top of the fence.
The plant I would use, would be an evergreen Clematis.
