Apply plugins depending on file extension in one .pipe chain?

Question

gulp.js

It is necessary that, depending on the file extension, this or that function is applied, because. various files come into the input

Src('Source/Templates/*/**/index.*')
   .pipe( Replace(...) )
   .pipe( IncludeFiles(...) )
   .pipe( /*Вот тут вот где-нить ext-контроллер впихнуть*/ )
   .pipe( RebuildFilePath(...) )
   .pipe( Dest('Build') )

What are the proven working options? (not in the style of "some kind of plugin, perhaps something can")
Wubpuk does not offer)
