amiga render mode for dos ega version of indy 3 an the last crusade last crusade possible?

[gabberhead]

the ega dos version of indy 3, has the same problem like maniac mansion and zak macracken have. the skin color is darker and dont look as goog as the amiga versions. i think the color of the whole game is also darker as in the amiga version. but maniac mansion and zac macracken have the option to use the amiga render mode on the dos ega version. now my question, is it possible to add this feature to scummvm, to have the possibilty also using the amiga renderer on indy 3 ega dos version? because now there are only 2 options which can be used. cga and vga. ega isnt even available in the render options. and vga i think, is wrong for the ega version. because, if u select vga, it dont change anything.
