Ah Ha!
The game editing website for schools and for some people to have fun with scratch.mit.edu I think is the site, Has created a Flash to HTML5 converter, they decided for anyone to use it anywhere, That’s why they put it on Github, You can use it here and give scratch credit. (Contributors File)

Here it is https://github.com/LLK/scratch-html5

Only question is. Will it work?

Or somehow you can download the .swf file and convert in into HTML5 on some converter website

You can do the steps on FlowLab then upload them to swiffy, Now you have a HTML5 FlowLab game, possibly you can upload it to wix or something. Someone should try this out
