Welcome to the forum I hope you enjoy it and learn something from the experts here, and there are a lot of them. I like the suggestion of adapting the trigger set and using a filler block with a draft. Both are simple and straight forward from those who know what they are talking about. Being a long time woodworker I have used filler blocks many times and done well they can be almost impossible to see without knowing they are there.
Best of luck,
Rob
