Well, i think i managed to incorporate both Mk6 and Seacat to Type 14.
I've expanded forecastle like on Type 15 frigates, to accomodate Seacat GWS-20 with STD director. AWS-1 radar was placed on main mast, which is moved afterwards to compensate additional superstructure weight (we need to keep good seafaring abilities for a small ship for north Atlantic). Mk6 with MRS3 director are placed on the place of the Limbos. There will be some weight reserve (Turret w/magazine - 37 tons, MRS3 - 8.6 tons, Limbos - 2 x 35 tons). Targeting sonars removed , HF/DF and Porker(?) moved to secondary mast. Maybe the ship is not pretty, but i hope it is not overweighted and retain its hull strength. We received limited range AD frigate for UK and commonwealth countries, but i'm not sure Leopards are not better (couple of 114mm guns had better range). There is no ASW weapons even for defense, but maybe we can add a single Squid in front of the nose superstructure? (I'm not sure i want to, it is 10 more tons forward)
