Republicans in power certainly don't want the ACA marketplace to thrive. But for the most part they don't want it to precipitously collapse, either -- though it's not hard to imagine the Trump administration pushing it off a cliff and then trying to blame Democrats ("it was collapsing already...").
While Republicans have no real wish to make adequate health insurance affordable for lower income people, they may prove somewhat receptive to the wishes insistences of insurers, out of long habit and because, again, they don't want the market to collapse. The Trump administration is reportedly considering a package of short-term stabilizers that includes enabling by administrative fiat a minor increase to age banding (the multiple by which older enrollees can be charged more than younger ones); allowing insurers to cut off coverage for late payers after just 30 days instead of the current 90; and tightening the standards and verification for those seeking "Special Enrollment Periods" (SEPS) outside of open enrollment.
