I don’t think they will actually remove the filibuster.

Most of the things Republicans care about such as cutting taxes and confirming judges can be done without the filibuster (see reconciliation and how the filibuster is no longer for judges).

For the Democrats, much of what they want to do is vulnerable to filibuster, so the Republicans will act like the legislative filibuster is sacrosanct, since it doesn’t really birth them and cripples the Democrats.
