Just a small update after I’ve used this for the first time this weekend. I do like the dust shoe and have made a small adapter that fits in the top and allows to connect the hose:
it’s threaded on the inside and allows the vaccuum hose to be screwed in it. The adapter fits snuggly in the dust shoe but can still rotate just so it doesn’t hinder any movement. I have another one at the other end of the hose and there plug in the vacuum cleaner. Works rather well.
One small adaptation I did make: put on some painters tape at the bottom. This does help in pieces of debris flying around and improves them being sucked in. Yet it’s soft and won’t damage your workpiece. Typically you have brushes/hairs on the end, but this is an easy to implement replacement 
added two close up pictures with and without the dust brush of painters-tape. Makes a significant difference:
