Selling Plugins

Hello, I have already programmed a Photoshop plugin and put it in the marketplace for free.

Now I am working on my second plugin. This time I want to sell it.

Now I am not sure if selling it as a subscription or for a fixed price works better.

Therefore my question,
may I publish the same plugin under different names to offer different payment methods?

E.g..
Name 1 : My-pluginname -->(for subscription model)
Name 2 : My-pluginname Lifetime -->( for one time payment)

both would get all updates, but the customer can choose if he prefers to pay subscription or one time payment


also, how are your experiences with selling plugins. Is it worth it at all?
