Is it possible? If so, what would the ramp length and height need to be?

the longer you spend at sub orbital speeds, the longer you're spending energy to counter gravity. Building a ramp and lifting it up slowly would only be feasible if you had cheap power to do it. but over all, you're still using most the same amount of energy to get there anyways.

also... if you're going to slow, you'll just fall back down...
