Position minecraft funnel?

I have the following problem:

Is there a way to arrange funnels in such a way that items that come in from the top left of the hole (also with a funnel) are distributed to all throwers? Warning: I only have 2 blocks of space upwards (tell me if it would work with three blocks of space) and the redstone is also important!

The redstone leaves you one level less than you think, as this stipulates the funnels as pointing downwards. So you would need a line with 4 ends in level 2.

With 3 levels it is possible: (The letters indicate where the funnel is pointing, U = below, N = north, E = east, etc. Assuming the hole is on the north side)

How long did it take you to take the picture?

For the picture without considering how to do it, maybe 10 minutes, is a screenshot of an Excel file with conditional formatting.
