The problem with Netjets is that they are not really a stepping stone. Unless something has changed, they wont be interested in you unless you have a few thousand hours as well as turbine experience. While you could certainly leave netjets for a major/legacy, youd have to get there first. Even then, while they are certainly competitive, small to mid size cabin business jet time doesn't put you necessarily any higher on the competitive list than an RJ captain.
Youd still need to solve the problem of getting competitive for Netjets which would be accruing the necessary experience. While 60K does sound a lot more palatable than 35K, those types of jobs don't come without putting your hours in. For a low time pilot the regionals are typically a necessary evil as well as a means to an end. If you want to get to the majors in any sort of a hurry there is likely no faster route.
