Yes, it's very possible. You don't even need blend modes. Copy the gradient sprite if you need it again later and use sprite_set_alpha_from_sprite().

thanks for quick answer - but as i sayd - i need it for shadow - and shadow comes from using same sprite just with image_yscale=-1
and when i use sprite_set_alpha_from_sprite() both feet and shadow have same transparency!..
so i was more thinking of using blend for shadow to blend two sprites together - but i just cant get it work!..

btw feet uses animation shadow just copyes same animation!..

It is simple, as said Medusar use sprite_set_alpha_from_sprite(spr_feet,spr_gardient) and write it to step event.

I don't think that will work. As far as I know you can only set the alpha once per sprite. This could be most easily solved with duplicate sprites. You could generate them at the start of the game, or as needed when an instance is created (being careful to duplicate them only once). There are also ways to achieve this with surfaces but surfaces increase the complexity of the draw event and might not be as compatible.
