Yes, my prediction is that the damage from the Biden-Ukraine scandal--and that's what it is, despite the efforts of NeverTrump bloggers to cast a shadow on Trump--will not be confined to Biden. It will be used by Trump to play up issues that will resonate with and expand his base.
Democrat corruption is one of those issues, of course. Every Blue State voter knows all about that, and this Hunter Biden story is crasser than most, because Hunter is such a despicable person and his father is such an enabler.
Democrat corruption also plays right into the issue of "privilege". What could be more privileged than getting to fire prosecutors who are looking at your ne'er do well kids? Only white Dems get to do that. But, come to think of it, who but white Dems get to lie about their ethnicity to get great paying jobs at elite places like Harvard--with no consequences? They even get to run for president without being challenged on that. But Trump's gonna change that once the campaign starts in earnest. Every middle class person who's paying through the nose for college tuition will hear about that, and about the liberal elites who cheat their kids into those colleges the middle class can't get into.
In a less direct way, this will also play into the immigration and tariffs issues. The nation will likely sense the connection between liberal preference for foreigners over the American middle class--and the Dem tendency to enrich themselves through foreign dealings. Yes, Hillary will be a topic (cf. link, above), and none of this will help the hoity toity Warren.
Finally, if Biden is eliminated before the primaries even start--and I'm betting on that--the Dem race will be a cut throat contest of extremists. Both Warren and Sanders will be competing for the biggest share of the same pool of liberal extremists--because that's who votes in Dem primaries now. Warren is a shrill, hectoring, extremist on virtually any issue you can name, and the country will be treated to her trying to outdo the unrepentant socialist Sanders.
