You mean, actually conservative?
Well, that depends on how you interpret "conservatism" honestly. Recently, I've been increasingly critical of the pre-Trump GOP/GOPe's vision of the party, which does not jive with the state of the country/world today or with current/future voting coalitions. They are bent on returning to a strict doctrinal version of Tea Party conservatism that began with Newt Gingrich's revolution and peaked in 2014. These are the ideological leaders of conservatism and the establishment GOP-Dennis Prager, Charlie Kirk/TPUSA, National Review, and Ben Shapiro/DW. Much of what they peddle is Reagan nostalgia, which is pure revisionism- Reagan compromised and negotiated to an extent that he would be called a RINO today, which also made him someone who could govern very effectively with a Democratic House his entire administration.
I don't think that's a viable path going forward, unless they are willing to become a permanent minority. There is a reason half of all young people support Socialism over Capitalism-the old GOP is unwilling to talk about difficult issues like student debt, housing costs, the insane wealth gap and the hollowing out of the middle class. You have to have a better answer to this than "shut up and slave away for Jeff Bezos". The old GOP also won't explain why corporations should hire foreign labor instead of US citizens at a below-market rate (think big tech).
GDP and low tax rates aren't a religion. Although Trump hasn't been as populist/pro-worker as he campaigned on in 2016, I view him as a transitional figure from one version of the GOP to another version, hopefully one that looks like what DR. RI described above-an interpretation of conservatism that actually "conserves" what makes America great.
The issue is I have no idea how you're going to fight the current GOP into moving that way. In the olden days of the last realignment (I'd say Reagan in 1980), a lot more seats were swing states so these Republican Senators and Congressmen had to get with the times or risk losing primaries or their general elections. Now, you have so many of these ancient GOP senators and congressmen that are never going to lose their seats as long as they appease their base so they have zero reason to get with the times and embrace a new GOP agenda. Even if all the swing district Republicans embraced this new platform, we've seen how the party as whole really isn't willing to buck much for their sake and will happily watch them all lose their seats because at least their own seats are safe.
So outside of a terrifying wave that we haven't seen since 1932, I think the GOP will have a lot harder time embracing this "populist and libertarian" or "Hawleyist" agenda. Think of how many Republicans even after Trump shocked the party, responded by essentially just embracing harsher immigration controls and absolutely nothing else.
