Dominions sprites in higher resolution?

[linlin]

just for fun, i did a try to work on dominions units sprites in a higher resolution to see what can be done..

i made a few test on some C'tis units..

now, i'm wondering if the game engine / mod workflow can accept to put bigger TGA files for the units sprites or if it can't be done without altering the engine itself..

here are my first test at different resolutions outputs..
