Adjusting depth and reducing diameter could do the trick, but finding an optimal that doesn’t cause a severe flow drop could be difficult.
To avoid modifications to the main fins it could be easier to cut slots on the pipe end at 45º. The interference with the tips of the third fin level could be milled out in the base, as it doesn’t affect the structure.
