It's too late for that. The case will be heard by SCOTUS in November. It's not a legislative action by republicans that's going to cause the ACA to be overturned, but there is a chance legislative action by democrats after the election could save it if the stars line up correctly.
It looks like the new justice will be Amy Barrett. Regarding the ACA she wrote: "Chief Justice Roberts pushed the Affordable Care Act beyond its plausible meaning to save the statute. He construed the penalty imposed on those without health insurance as a tax, which permitted him to sustain the statute as a valid exercise of the taxing power; had he treated the payment as the statute did—as a penalty—he would have had to invalidate the statute as lying beyond Congress's commerce power."
She went on to state she "vehemently objects to the idea that a commitment to judicial restraint—understood as deference to democratic majorities—can justify a judicial refusal to interpret the law as written."

The fiery ACB (just like Scalia) is precisely right; Roberts did craft the majority opinion he did to "save the statute."
But that does not mean that there were no other constitutional bases for the opinion.
That part of Roberts' rationale is squarely consonant with Harlan's dissent in
Lochner and C.J. Hughes' majority opinion in
National Labor Relations Board, each an exhortation of judicial restraint.
The debatable issue is this: Was the ACA Court activist by upholding the ACA or would it have been activist had it struck down the ACA?
Is the Court activist or not when it "rewrites" a statute or formulates a strained construction of it so that it passes constitutional muster?
Justice Kennedy's quip comes to mind: An activist Court is a Court that issues an opinion you don't like.
