Yes.  I did exactly this when I wanted to convert some MPEG TS dumps
(containing just the PIDs of the TV channel in question) to VDR format.
I hard-coded the file name to the vdr binary to the place where it would
open the DVB device.  Note that vdr will be receiving the stream at much
higher speed, resulting in very many dropped frames in live view.  I hit
the Record button very quickly after starting the patched vdr.  I added
some junk to the beginning of the MPEG TS file to get the start of the
payload recorded.

I'm not sure if the simple modification is enough.  You may want to
somehow throttle the reading from the file, if your plugin can't
keep up with the data rate of the file system.  Maybe read from a named
pipe that is filled by another process with appropriate delays.
