You can go that route and there’s tons of great schools.
Or you can go to - many a fine public (with or without Honors and depends on what they want to study) - but an Alabama, Florida State, Ole Miss, Ms State, Miami Ohio, Mizzou, UTK, U of SC - and really so many more - and even some privates including fine mid size or LACs.
With the list I mentioned (and others), you can go much cheaper than $200K a kid…I’m less than half that for two kids and my kids schools both have incredible programs…one is a part and one isn’t…but would have had opportunity should he wanted.
I guess it’s the bummer of twins (four years of simultaneous expense). But $285K and great assets (that will be your downfall) is a nice problem to have too 
In all seriousness, if grad school is in their future, you might want to plan further out than just four years.
Good luck.
