No, you don't need ASM, just some knowledge about the following data:
$18010 - Sprite frame data pointers
$1834A - Sprite frame pattern data
$18816 - Sprite frame data
The sprite frame data defines the tiles that a sprite uses and the palette that each tile uses. The sprite frame data pointers point to where each sprite frame starts in the frame data. The sprite frame pattern data says where each sprite tile appears onscreen in relation to the sprite's coordinates.
So with this data, you should be able to add sprite tiles to any sprite you want, so long as you aren't adding to the overall number of sprite tiles (read: if you add a tile somewhere, you'll probably have to remove a tile elsewhere).
This all is probably still difficult for ROMhacking newbies, but it's not an impossible task without ASM knowledge. Please don't jump to conclusions if you haven't looked into the data yourself (this is directed to those who've replied to this thread already, not Eli).
I hope that helps.
