If that lens tube has a 7mm thread, it might fit in a #11 if the pitch is right! A bit of a pain to try it though. I've thought a wider angle lens could help fix the #11 vignetting, but I've not been able to find a source.
Also, the #11 has an IR filter on the rear element of the lens, not in the lens holder over the CMOS. So finding one with an IR filter adds to the problem.
