Everything is possibel but sounds like a bit of a wast of time...
To what advantage would it have appart from a increase in weight
Much of what is done for fun and for research is, on one hand, a tremendous waste of time and on the other hand extremely necessary.
This is after all a hobby and if this project has captured the OP's imagination and he is having fun with it then who are we to say it's wasted time.
And just because you don't see an advantage to the project does not mean there are not advantages. Personally I can see applications where independantly powered wheels would prove a distinct advantage. And if they could be coupled to a programable controler the advantages multiply rapidly. And, really, weight gain will not be all that much if done right.
