Fred hosts a lot of talented artists anyway. Of course it would be another art style, but Shilin for example has very nice art. And the storyline is already finished, you just need to turn it over to someone who has already successfully created visual novels.
Hell, I think some smaller studios would even be interested to create a megatokyo VN! Especially if you give them a part of the kickstarter money.
And yes, it wouldn't be exactly as Fred envisions it, but sometimes you need to let things run their course. Maybe his calling is being the mastermind behind the story and letting others cast it into games or movies
You could even make a poll, whether the kickstarter backers would mind another artstyle by another artist. If you choose a good one, they might be just fine with it.
