Alex Desk...to Standing desk?

Has anybody succeeded in turning the Alex Desk (132x58cm) into a standing desk by adding a different frame underneath?

I really like the desk with it's drawers, but I'm about to start studying a degree from home and since I have ADHD I think I could benefit from having access to a standing desk.

Thankfully I can access disabled student allowance and would like to go into my assessment with them with options to convert my current Alex desk, instead of having to replace the whole unit, as I don't have room to store two desks in my home.
