Sure. Sell them on ebay and buy higher density memory.

Unless the motherboard was specifically designed to accept a custom
expansion slot (a few high-end workstation and server boards are),
you're SOL.

Unfortunately the electrical characteristics of memory controllers
just make expansion cards that plug into the DIMM sockets totally
impossible these days. Even getting 4 DIMMs to work on can be
somewhat tricky under many situations (most low-end boards you'll see
only have 2 DIMM slots). It would also be totally pointless to put
memory in a PCI expansion cards, since the PCI bus tops out at 133MB/s
in most current systems, while a single DIMM of current memory gives
you 3.2GB/s of memory bandwidth.

In short, put the highest density memory in and go with that. With
the other sticks, either find another machine to drop them in, return
them or sell them, because they aren't going to work in this system.
