It sounds like you will have the normal "line in"
You then propose to install a flexible "line out" which will hang lower and clearer - thus allowing you the bleed from the far end - and hence remotely.
THAT is something I never once considered. I have hung in awkward positions to get in there to bleed. I always found a way - like the third time of the day -- Thanks TSBL. Of course I forget for the next time.
ARe you going to remove the remote line after bleeding? Doesn't that add air to the system? If you are going to leave it hanging - is that safe? Assuming that the line is closed and pressurized, wouldn't it be tensioned by the high pressure fluid? I would doubt it would remain just hanging there. What would it interfere with?
This sounds interesting as a concept, but I would really like to think this through.
