There probably won't be modellers plans for the F100 s in the UK but some research in Spain might turn up something if there are any model boating Forums there. The naval authorities tend to keep their designs secret!
However, in the September issue of Model Boats on sale this week there is an interesting article on building one of the RN Daring class destroyers although there are no plans for it. And of course there is a long running series on building a museum standard model of HMS Daring by Dave Wooley.
I think the Triune is a good place to start, then you can tackle something a bit more ambitious using the experience gained.
