It is possible to change the screen size, but not while your program is running. Only once.  
This topic outlines how to do it:

> If you type namespace userconfig { export const ARCADE\_SCREEN\_WIDTH = 320 export const ARCADE\_SCREEN\_HEIGHT = 240 } Into the java script editor, you just changed the screen size. You can input ANY SIZE! Why does nobody use this! I can make a game in 4k! (with low FPS but thats besides the point) There has been MANY times where I wished this was possible and now I find it IS?!??!?! Anyways I just wanted to share this so no one suffers as I did.

It only works in JavaScript, not blocks, so I would make a copy of your project before going into JaveScript and trying this.
