Yeah that is very possible but your registration
Will not be done on the official steemit website
And the reason why is because you must have
Phone number and email address when you
Want to register directly on steemit.com but
If you do not have phone number or email then
You can use other services that offers steemit
Account opening

Busy.org have a features which you can use to
Create a steemit account instantly but the
Service comes with a fee which is the account
Creation and it can be as nuch as three steem or more,blocktrades.us also have a feature that allow you to open a steemit account for a fee

The benefit of opening the account directlt on
Steemit is that you will not need to pay any fee
And even when they approve the account you
Will get 15 steempower on your steemit account
Whcih will make your account useful,then you need to know that you may have to wait for
Two weeks before steemit will open an account
Which you registered directly with them
