No.  I have changed a lot of brake hoses over to braided SS and it isn't
that bad.  One trick is to use a brake fitting (cut off from a donor/wrecked
car) to help keep the drips down.  Also, I have found that plastic valvestem
aircaps work on hardlines.

You can also wedge the brake pedal down - that is supposed to keep fluid
from leaking out through the reservoir.  I haven't needed to do that,
though.

If you use air to "blowout" the fuid in the lines you will only succeed in
making it extremely hard on yourself when you try to get rid of all the air
later.
It really isn't that bad.  Wear rubber gloves, use a catch pan, work
swiftly.  No big deal.  Pressure bleeding with one of those hand-pump
plastic bottle things works great to fill the system quickly.  I still have
the best results for final bleeding doing it the old fashioned way with a
friend:

Person at the bleeder: "Pump three times and hold"

Person at the pedal:"OK, holding"

Person at the bleeder - open bleeder, let fluid escape out tube into
container, close bleeder

Reapeat as necessary.
