[HELP WANTED] How to modify Microsoft IME Keyboard?

[RedPandaCommandaFps]

So, I'm working on a novel passion project right now and I have a custom language I want to insert into the text of the book. However, some of these symbols use a similar concept to Japanese Kanji. I was wondering, is it possible to make a template and modify the existing keyboard to allow for my characters to pop up when I type in a certain Romanized letter combo. So for example when I type Shinzo into Japanese IME I get 心臓. I'm asking does anyone know how to make a layout where I can crate my own Romanized entries to correspond with my custom fonts. Which I would also have to learn how to make and add in but one problem at a time.

Spam posting the same question in multiple different sub forums is not allowed especially if they don't fit into the sub forum posted in. I would post this on forum dedicated to creating custom fonts/characters or a keyboard/keyboard layout programming forum. What you're trying to accomplish is pretty niche and will most likely require a custom program or custom programming of the keyboard.

Wasn't trying to spam but I'll take your advice. Wasn't certain where to post it so I'd figured I'd.ask around.
