Hopefully the Sovereign II will be OK, but yes, there's every chance you'll be changing caps in the RP18s.
Remember, the blue Mullard/Philips types (translucence sleeve, normally blue but sometimes off-yellow in very old sets) will probably be fine. I have seen RP18s with the Philips/Mullard types, and they were all good.
One day, I'll write an article about the capacitors found in these old transistor sets - a companion to my transistor and potentiometer articles. Just need to finish the time machine first
The RP18s have a lot of AF11x types to sort. I'm still waiting for a comeback from zapping them - never had a complaint, and I've been doing this for many years now. The 2 transistors inside the Gorler front end are reliable types - no need to go in there... I've no experience of the Russian substitutes, but I'd expect them to be fine in the AM sections. The FM IF amp might be more fussy about transistor types - let us know how it goes.
Good luck
