It is possible to store files in Blue Prism work queues using the Binary data type. In a calculation stage, use the LoadBinaryFile() function to load the file as a binary. When you need to use the file, use the Write Binary Data action in Utility - File Management (if you don't have that action, you can create a code stage instead).
As far as space considerations, the binary data is being stored the same as other data in the work queue item. When you delete the work queue item, it will free the data as well.
I don't think there are any performance issues with doing this, except for slightly longer load times when you go to retrieve the work queue item, though I don't think that would be much of a problem unless you had relatively large files being stored. The alternative would be to use a file share to save the files, and then store the path in the work queue instead.
