Actually, ues, you can.  Instead of using a static Fileset, you can
configure Bacula to source a script that generates it on the fly.  You
could create a dynamic-fileset script that excludes all files over a
specified size.

Here's an example from
http://www.bacula.org/manuals/en/install/install/Configuring_Director.html
of a dynamically-generated Fileset:

Include {
   Options {
      signature = SHA1
   }
   File = "|sh -c 'df -l | grep \"^/dev/hd[ab]\" | grep -v \".*/tmp\" \
      | awk \"{print \\$6}\"'"
}

So you could simply create a dynamic fileset script here that
enumerates all directories and all files not exceeding a specified size.

Now, the above is a bit of a brute-force solution.  I have not
personally tried this refinement, but I see no reason it should not
ALSO be possible to create a static fileset with a dynamically
generated exclude list, something like this.

FileSet {
  Name = "Dynamic Exclude Set"
  Include {
     Options {
        signature = SHA1
        File      = "|sh -c 'find /home -size +10G'"
        Exclude   = yes
     }
     File = /
     File = /home
     File = /var
  }
}

This example should result in automatically excluding any file 10GB or
larger located anywhere under /home.
