Can a good hybrid be made into an adequate good touring bike?
By adding dropped bars and going to bar end friction shifters?
It seems that it would be cheaper for me to get a hybrid because they
have a 26" tires, canti breaks, and low gears. These three things add
a lot of cost to a bike.

I would want to be able to add front and rear bags and I am not sure
if racks would fit.

The touring bike I like would cost 4k and is more than I can afford.
