That is a neat MM option! But $80 is pretty steep cost to save 2 minutes, and introduces 4 more screws and a potential failure if it came loose... I'd be nervous, especially considering how much more stress you're putting on it over stock with that insane motor! I'd probably play it safe and keep it one solid piece for durability instead of the trade off for a bit more convenience, but it is definitely a cool looking piece and probably works great...
