I don't know how you plan to make 0.2mm fins: that would be very hard. Otherwise, your ratio of channel to fin (4:1) is on the low side. Compare the ratios of existing HSF to get a better idea. As I remember, 8:1 or 10:1 is closer to ideal.

You should increase the area to cover all of the baseplate, i.e. 50 by 50mm: you'll need all the cooling that you can get.

BTW, you might want to look at existing skived fin heatsinks. You can find many in the OC roundup.
