I did back when I worked at Man Group. This was before Workato had any recipe diff tools and all deployment had to be done in Recipe Lifecycle management.
I used Octopus Deploy Custom Powesrhell steps to call the Management API and pull down project manifests into a Git Repo and create a pull request. Once an approver had signed off that request it was then deployed to the next Environment. The final push to prod could then be done using one click in Octopus deploy. Everyone involved was informed and given necessary links via Slack.
Although the solution worked well, it's not something I would recommend to my clients today. It would be very difficult to replicate and offers very little over a semi manual process using the current tools. Workato's lifecycle management is streets ahead of where it was 3 years ago. It's not perfect, but it's also not worth the effort of replacing given how fast it improves.
