Even if you could in theory help, which we would need the help of users who did remember the game and could help me out with the details, recreating the game would take more than 3 years minimum.
The reason for it?

The game was entirely in flash - it needs to be recreated to html5 or webGL and done in unity

The assets for the characters and all their clothes had 6 different sides, so every single hairstyle, body and item would need to be drawn into those 6 sides

ALL the assets are gone - there isn't a single sprite (image) of anything from the game, not a button, a phone, an icon, anything. Every single image from the menu, to the bedroom, to the phone... all of it would have to be recreated and readjusted time after time after things are "put" together.
In theory it sounds easy, but the web avatar was already really complicated to make for similar reasons. You're grabbing a flash game and making it html5 and with every asset recreated, the amount of bugs and possible glitches it creates and needs to be perfected is giant.
I won't say "no" to a remake, I might want to risk it and try it, but realistically I don't see it coming any time soon at all. Winx Adventure is already quite challenging and the game is sort of working already.
