I doubt you will find such items, because they would be such low
quantity that it wouldnt pay a manufacturer's start up costs.
However, if you are willing to spend a little time screwing around
with a soldering iron, you can make your own.

Look for some Dip headers, either straight pins top and bottom, or
some that are made like component carriers. Get the nice
machined pin types that have small round leads about .2" long or
longer on at least one side. You can also use regular machined pin
IC sockets. Dont get wirewrap types or the types that have
flattened pins. Get the types that have small round pins.These will
plug into a breadboard. Now you can use glue or whatever to mount
stuff on top, and wire it to the header or component carrier. I've
been doing this for years. The last one I made was a 28 pin carrier.
It has room for a pic chip, and also the crystal and caps etc. This
way, the pic chips leads are protected because the carrier is what
is always plugged into the breadboard or programmer. You can just
as easily  put switches, small connectors, voltage regulators, or
whatever you like on them using just solder and glue if neccesary
for mechanical strength. You can do the same thing with header
strips, but it will be sip style where you plug one strip into each
side of a socket or just plut it into a breadboard.

Its a litte tedious building up something with a dozen parts on it,
but its worth it if you need something that you will be using
frequently.
