I cant remember size if it is 8x6 or 8x 9 as there are 2 out there with this brand... but this is what it looks like and being last years model the price is slashed in half...

The shed looks really nice. But personally I am a HUGE penny pincher and couldnt bring myself to buy a shed when I already have one. But if its within your means and you would like to go larger then yes, I would say it could be converted easily. Plus you could hose it out easily.
