I'm sure it would alter the look but I think it could potentially be an improvement. From what I've seen, sometimes the 43's bokeh is a bit busy for my tastes. It's the main reason I haven't pulled the trigger on it. That said, of the current normal lenses it's my favorite and I might still end up getting one.
When the DA 15 got the HD refresh, the switch to circular blades took away from those great starbursts it's so well known for. Makes me wonder if a Frankenstein 15 could be made that has the new HD coatings but with the old straight blades.
