What's your definition of long? The 9, 49, 62 & new 94 would be the only routes over 10 miles. I think the 94 will be fine as is, routing-wise, and should be shared with Kedzie. And for however long the pandemic is going on during the pilot, they won't actually need extra buses.
If you're at Divison/California or south of that point, you're either equidistant btwn the Blue & Green or closer to the Green Line, making the Green Line the "faster" option. However, if they're banking on the 94's CTA connection being more attractive than the 70, 66 or 65, they're sorely mistaken. I think @artthouwill's statement that this was more an attempt to streamline Kedzie & California rather than get Humboldt Park riders to take the Green Line rings true here.
