An easily detachable, magnetic dome diffusor for the larger sized B1/B1x strobes would be really useful. It would create more even light across softboxes, or any modifier designed to make a larger, softer source.
If this were coupled with a clear glass cover to replace the stock frosted one, you probably wouldn't lose much power from the strobe.
Add a magnetic mount for the 10cm mount from B10x, B1x etc. so it easy to add Filter, grids etc. to the flash. So it is possible to use gels with a softbox.
Make a thin border to not loose any light and that it is not bigger than 10cm.
