Changing "world to meters" during runtime

I’d like to be able to change the “world to meters” value from world settings during runtime. Is there any way to access this parameter in blueprints? Or does anybody know another workaround for this? I looked everywhere but couldn’t figure it out.

In 4.9 you are finally able to set it directly in BP using SetWorldToMetersScale from Input>HeadMoutedDisplay.

There is also stereo w2m=xxx console command, which causes similar effect.

cool that console command works indeed.
Does anybody know if its possible to fade the value?
