With the LC arriving soon and looking great, Lexus should base the next generation RC coupe, on the next generation IS, rather than using IS and GS parts for it.

That would avoid cannibalism between the LC500 and the RCF, especially since they share the same engine and would solve one of the RCF’s biggest problems, its weight. It should also leave the V8 for the bigger cars, and use a 6 cylinder engine with a few turbos attached to it.
