Possible to use latest Steam SDK via dll binds?

UDK has a very old version of the Steam SDK, which doesn’t include things like the Steam Inventory Service, etc.

I’m wondering if it’s at all possible to create dll’s (which we can use via DllBind) that can link to the latest SDK and use that (in addition to the old one that UDK is already using). Without needing to recompile the UDK exe.

Any ideas?
