Sorry, Doug. Hoses are a lot more expensive than steel tube and are serious reliability issues, even on airplanes where cost isn't usually part of the equation. The only places Boeing used hoses is where there wasn't a reasonable alternative.
CRES tubing is a lot cheaper than multi-layer flexible hoses and was used on both Concorde and TSR-2, which had 4000 psi systems. Having been retired from Boeing for a while, I don't know if the 787 went to 4000 psi. I know they were considering it.
Bottom line is, if the actuator body does not move, hoses are a waste of money. Rigid lines are cheaper and more reliable.
