Is it possible to embed TCL directly into a Cisco startup-config?

Is it possible to embed TCL directly into a Cisco startup-config? From the (lack of) information I'm finding, it doesn't look do-able.

I have a tool that generates Cisco configurations based on some simple criteria. I'd like to include in this script a version check that will fail if the installed version of IOS is less than the minimum required.

I guess the "real" question is: Is it possible to construct a startup-config that completely fails to load if the IOS version fails the check?

I'd still like to know about TCL in general. I know a separate file can be prepared and parsed, but I'd like to have it all in a single startup-config configuration script.
