^If Chessington has the money, anything on that scale would be fabulous. But it shall be said, I've never been to Chessie, and I know next to nothing about the park, so I don't know what it would do to the atmosphere of the place.
From what I've heard, something similiar to Lisebergbanan would suit the park (Schwarzkopf steel coaster). Terrain hugging coasters doesn't look as scary as other rides, and are exciting without being too intense.
And I would like to echo the words GCI Wooden Coaster. Troy at Toverland in the Netherlands is called one of the best woodies in Europe, and standing at 33 meters, it's the tallest or second tallest (RCDB doesn't list the height of (the very appreciated) Thunderhead at Dollywood) GCI coaster, so the company offers coasters that can fit under most height limits. Not to mention, GCI's coasters are recognised as some of the most beautiful coasters around.
Intamin AG also make some fabulous wooden coasters, but they are taller, more expensive and more thrill-orientated. Still, even the smallest of the modern Intamin coasters, Balder at Liseberg, is voted the best wooden coaster in the world several times. Intamin also offers a junior wooden coaster.
As for flat rides, a Huss Topple Tower sounds like a good idea. There are tons of different flat rides out there, and any well-themed flat ride that you don't see everywhere (unlike Topspins, every park has one) would do great. That being said, even an ultra-common flat ride can be very good with sufficent themeing (see Talocan at Phantasialand, for example).
