I'll chime in...
If the conditions are right you could try it.
I'd fly in the early morning on a windless clear day.
If windy, flying into the wind to start would be best as that is when your battery would be drained quickly and not so much on the return.
Also don't try it in one flight, make multiply flights to test your range and take baby steps to increase your range with each flight.
Another thing to remember is that LOS also means transmission from the controller to the Typhoon and back.
Even if you can visually see the H, if a tree gets in between, you could loose feed in which case you would have to move so there is a direct line between the controller and the Typhoon.
In my case I live on a hill and can usually reach 5000'and have reached 7100' on a clear windless morning.( White route in maps below)

Here is a long (6 min) video of one flight reaching 5100 '
and the flight path

Anyway, good luck and be sure to post your results as that looks like it could be a nice video !
