No. Module imports are resolved at static analysis time,
before any code starts executing. That is when all references
are resolved and the expression tree of the request is built
(which may include code from imported modules).
XQuery is a functional language, and one of the principals
of a functional language is that there are no side effects
during execution. Dynamically loading modules would be a
whopping big side effect*.
*Yeah, we cheat a little big with xdmp:set and map:map,
but dynamically loaded modules would change *all* the rules.

I'm fairly sure this isn't possible, but I might as well ask. Is
there any way to import a particular module at runtime?
I know this won't work, but it shows the idea:
import module namespace blah = "http://blah"; at $filename;
It won't work because import statements must come before not only
functions (and code, in the case of a main module), but before
variable declarations as well.
Can someone confirm?
Thanks,
Eric
