No, it's not possible. The 7000 series only came in a model 1 or a model 3; there was no model 2 limited keypad. You could probably swap out the XE control top with a standard control top, but you can't turn a model 1 into a model 3, as it requires a different VOCON which must be matched with the RF board. And you'd need to change the model #, which requires means that are not discussed here.
Sell the radio and buy something else.
