Disney already said they plan on doing a SW movie every other year, so the next trilogy will probably begin in 2021. They're also doing all these one-off movies to expand the universe. Han Solo movie in 2018 and (I think) Boba Fett movie in 2020.
The MCU isn't ending until AT LEAST 2020, as they still have released scheduled until then. If movies like Black Panthers, Captain Marvel and Ant-Man and the Wasp are big hits, they'll keep the MCU alive longer with these secondary heroes. Let's face it, Hollywood doesn't make the money it once did, and SW/Marvel/DC are cash cows. They'll keep them going as long as they can.
Point being, don't assume HT will get caught up and not be busy anytime soon. They're already running on a year lag to get figures out. Spider-Man Homecoming figures aren't due to be released in HK until 3Q 2018. Even if no new films get announced the MCU ends and SW takes a break, they'll still be busy for 5-6 years minimum before they can find time for the cockpit. By then, they'll probably just cancel it.
