Sounds like a very sensible idea to me. Just make sure your gender
benders (gender changers) are easily identifiable from null-modems. I
have a lot of RS components little double ended back-shells that allow
you to put either gender DSUB on each side and you can wire up any
form of connection you like, including just a simple gender changer.
They work fine but I invariably recover them later on and when I need,
say, a gender changer I frequently used to pick up what I thought was
one and end up with a null-modem. Wish I had the discipline to not
rush ahead and just label the things :)
