Replace existing Plastic dome skylights with new Double Glazed units

We have 6no. old plastic dome skylights that need replacing, into a concrete tile roof. We would like APL or Velux (if they fit) double glazed units. There are 3 different sizes, rough measurements are 3x small --- x long --- , and 1x large --- . No change to internal ceiling linings. Just external replacement. 5 have existing lead flashings that look ok - but new flashings might be required. To be confirmed.
