I think as much or as little effort as the OP wants to put into it. One thing to consider is that some cuts may not be possible due to existing cuts which could cause severe weakness. I can take lots of photos to help though and can provide measurements where needed. I do think a good display gun can be achieved especially if displayed in a Perspex faced Bren chest A'la Laidler! Peters display is one of the best ways I've seen to display the Bren.
