The fact remains thatExpecting to switch from an MFA site to an e-commerce site that is profitable out of the gate is most unrealistic.you're not going to learn anything of value re. visitors' responses in a mere 2 days.
If the cited revenues are of such great import that they cannot be foregone without being offset by other new revenues, then you'll need to test the e-commerce site separate from and concurrent with the extant MFA one.
To me, it seems like a promotion of BigCommerce platform, nothing else.
Maybe I'm looking at this the wrong way, but is the number of days a business has been open the real issue here? If we're trying to predict future success by talking about conversion rates, then it really doesn't make any difference if we're looking at visitors that come in the next five minutes -- or the next five months. A conversion rate is a conversion rate. Sure, you'll need enough visitors to provide a statistically relevant sample size. However, I think 500-1000 visitors is a pretty decent sample. I know some people use Adwords just for this purpose -- to quickly see what the conversion rate might be for a given product/market. If they can get 500 visitors in one day, the test is over.
Do the best you can - as fast as you can - then fix it later.

I would generally agree with this but I think this case is somewhat different because he went from one type of site to another. Obviously the visitors that come the first day are different than the visitors that would come later. Like if I had a donut shop that had 200 customers a day and the suddenly changed to selling hotdogs my conversion rate would be close to zero. However, once hotdog lovers found out the donut place sells hotdogs that conversion rate would go way up. Not saying this is exactly what's happening here but switching format but relying on the same traffic sources could skew the results.
