I think the simple answer is "no." In order for Trump to be impeached, that would mean that a Republican-controlled House passed articles of impeachment against him, and a Republican-controlled Senate adjudicated him guilty. If it got to that point, Trump's political capital would have to be already at zero.
To reach that point, Trump would have had to have done something so incredibly stupid that the folks in Congress feel that he is weighing down their chances for re-election. Examples of this include: Mueller's investigation reveals hard evidence that Trump entered into a criminal conspiracy with the Russian hackers and/or Wikileaks (or accepted something of value from foreign nationals to further his 2016 election, breaking campaign finance laws, and possible RICO and other laws); Mueller's investigation reveals that Trump broke US laws before the election by performing money-laundering services for Russian oligarchs before the election; Trump starts a nuclear war with North Korean that results in millions of deaths in Seoul; Trump starts a war with Iran that turns nuclear and results in millions of deaths in Tel Aviv; Trump's economic blunders cause the stock market to crash, just like it did under Hoover.
