Skylanders Game Idea: Elemental Switchers

Here's an idea for a Skylanders Game. It's called Elemental Switchers

Now I bet some people are like "I like the design of the character but I wish he was a different element".

For this idea for a game, Players now have the oppitunity to switch different elements for the brand new type of Skylanders known as the Elemental Switchers. In order to switch the elements, they must detach the detachable elemental bases underneath them and add a different elemental base underneath. With this brand new ability for your new Skylanders, you can experience brand new powers. Over 20 different attacks for just one Skylander.

Here is an example of one of the Elemental Switchers. His name is Rollno, a rhino dragon. His regular powers are to just roll and go for some bad breath. But if you put him on the fire base, he'll leave a trail of fire while rolling and breath fire. While on the Earth base, he'll roll in spikes similar to some of Spyro's Earth related attacks in the Legend of Spyro Dawn of the Dragon and barf a mudslide.

What are your opinions for this. Do you like it? How could I improve?
