Instead of two 10-sided pyramids glued to each other as a skewed d20, why isn't a dice with two 5-sided pyramids sandwiching two 5-sided rectangular rings possible as a skewed d20?

@henryseg I agree it isn't a skewed isohedral, but it would be a skewed d20 I would prefer over the double 10-sided pyramid d20 dice in the skewed Dungeons & Dragons dice set, if it is feasible of course. :)

@henryseg last night I thought of two alternative skewed dice (because insomnia). The first is a skewed d10 of two square frustums glued to each other, which is kind of isohedral when skewed. The second is another skewed d20 alternative of two hexagonal frustums sandwiching a 6-sided rectangular ring. I know it is not pretty and not isohedral, but in case the skewed two 5-sided pyramids sandwiching two 5-sided rectangular rings d20 doesn't work, I would then still prefer the two hexagonal frustums sandwiching a 6-sided rectangular ring over the two 10-sided pyramids glued to each other as a skewed d20. I just realised I really dislike pyramids for some reason and I do not know why...? o_O
