I reckon, it would be great to see a 2d, side-scrolling chat area, where the current images are used, no extra animation or images needed except maybe for some facial expressions, and speech bubbles appear above your bimbo showing what you have typed.
There could be different areas, which are basically just backgrounds, where you just move your bimbo about left and right, and chat to people.
Easy as pie.
Best thing is you would get your bimbo seen real easily.

Hope this helps!
