Transparent or translucent mob entities?

[22i]

we have transparent nodes like these cave crystals from LegendofMinetest subgame

is there a way to make mobs transparent or translucent like this?

How can this be done?

Partial transparency (alpha ∉ {1,0}) for entities is not supported by Minetest.

If you want to fake it you could try dithering the transparency, but it will probably look really bad.
