Yes and no. Very similar optical designs, but neither are known for exepctional bokeh. THere are tow reasons for this:
1) The focal length. The longer the focal length, the easier it is to get subject/background separation.
2) 6 aperture blades. Unless you shoot close to wide open, the background would be rendered as a series of hexagons.
You can see this 6 bladed aperture effect with your 50 already, just stop it down to f4.
Don't let me scare you away from the 35 it is a great lens. It is known for it's sharpness and usefulness, not it's bokeh. I don't know many lenses in that focal length range that are (with the exception of the sigma 30 1.4) so if that is the type of photography you want to do, consider it. If you want sharp images in low light, the DA 35 2.4 is a good selection. The DA 40, for me, is worth the cost in money and 1/2 stop because I like the way it render's better, but the DA 35 is no slouch and will really help you out.
I feel like I am repeating myself... I'm not sure where else to go with this. You want to replace a strange zoom range.
Furthermore I'm not sure how useful the 70 would be to you.. you don't seem interested in portraits, which is what I see that lens really excelling at. Your 70-300 has the surfing covered, so if you are looking for an indoor lens that is much wider than the 50, I would strongly consider the 30 1.4, as long as you know you like that wide aperture look.
One word of caution though... I find people who shoot at the extreme end's of their zooms do so because they actually want to go further. Have you considered something wider than 24, and how useful that would be to you? There is always the DA 21 or DA 15, which would bring you into a whole new landscape territory. The DA 21 is not very fast, but a great indoors length.
