From a project management perspective, spinning up a project to have your software engineers write such a plugin might be something your company wants to spend resources on, or it may not. If your process genuinely needs such a tool, and nothing is available in the Atlassian Marketplace that suits your needs, then finding a project sponsor for an internal initiative may be a reasonable next step for you after you exhaust your research efforts on what's already out there in the ecosystem.
