Here's something that would stay if it were reformed.
Insurers would no longer be required to cover a set of 10 essential health benefits as they are under the ACA, but some ACA elements are kept in place. Young adults can stay on their parents' health plans until they turn 26, and the ban on lifetime coverage limits remains. Instead of allowing insurers to charge older customers no more than three times the amount what they charge younger customers for the same plan, that ratio is widened to 5:1, which means cheaper premiums for younger enrollees. The GOP plan also keeps the ACA's $700 billion in Medicare cuts, as previous House budgets have done.
