I would expect it to be very difficult unless you have access to
suitable glass material, lens design, and manufacturing instruments.
Photographic optics including enlarging lenses do not consider to
minimize aberrations in the UV range. In addition, usual crown and
flint glasses do not transmit UV light of shorter wavelengths very
well, especially if many elements are used.
