Power BI Dynamic Language Translation.

I'm trying to solve this translation issue for an internal web application, which means that we have control over how the reports are built and what components in power BI desktop used. With these prerequisites, isn't it possible to handle the language using javacript ? I've just had a quick look at the DOM and done some simple tests and it seems like it could work. 

What I'm thinking of doing is for each component (table, slicer and so on) that we use in our reports I'll create some sort of selecter in javascript which extracts the values, i.e. for a table I'd extract the column headers, and pass them to my own translation service which returns the translated value and replaces the original value.

Someone must've thought about this before so I'm hoping if this is another dead end then someone who knows hopefully reads this and stops me. If not I'll probably move forward with this. If it works I'll try and package the solution so that other people embedding reports can use it
