not really possible, I asked amal the same
I dunno if something changed tho, it was a while back
basically the titan has to be a bit thicker on the sides for sealing, and this form has “the most magnet” in it
If it’s wider and thinner, the outer walls stay the same thickness but you add more titan on the top
it’s close to a ball and balls have the smallest surface area, so any change basically makes it’s titan/magnet ratio go down iirc
