I assume you mean Meego Harmattan which was used on the N9, successor to Maemo 5 used on the N900? Real Meego was never used on Nokia phones according to some people - but that's all history now.
There are some themes available for Android which provide the same look as MeeGo Harmattan but I don't think anything provides the same Swipe UI.
If you want to use Meego then the closest thing is Sailfish OS which has a similar Swipe UI and is based on Meego Harmattan from the N9. Not many phones are available with it - you might be lucky and find an Intex Aqua Fish on ebay! Or you can buy a Sony Xperia X and install Sailfish X on it.
It would be nice if HMD could work with Jolla to make a version of Sailfish for Nokia phones, but I doubt it will happen soon, HMD probably have higher priorities (although I'm sure all the staff know each other since their offices are very close to each other!).
