Of course it is possible! I use this kind of movement in all my tile-based games. It's kinda simple: First I store the sprite's coordinates in map coordinates - like x=1000; y=1000 then, I check 6 points in each sprite for collision detection - top left, top right, bottom left, bottom right, middle top, middle down, middle left and middle right (get each coordinate \ tile_size and check if it is in any "non-walkable" tile) and this doesn't impact your game performance at all. Sorry for my bad explanation, but my English is NOT that good.... Hope this helps....
