Audio plugin, that can be used to mix a track

I am looking to create a custom audio plugin, specifically designed with Pro Tools, and other major DAWs in mind, for the purpose of mixing audio tracks. The plugin will offer a variety of features and effects to customize the sound of the final track, such as equalization (EQ), dynamic range compression, side chain, multiband compression, delay and more. I am aiming to achieve a vintage sound, with warm tones and vintage analog-style quality. The ultimate goal of this project is to create a special audio plugin that will provide a unique and distinct sound that stands out from the crowd.
