Tariffs are really only justified as a way of matching the tax gains made by other countries that employ tariffs, mutual free trade is always beneficial for individuals in both nations in the long term and almost always beneficial for the nations themselves except a few very small nations with poorly diversified economies.
Excise taxes are part of an already flawed tax system, I agree with the occasional utilitarian tax in the short term simply because we have not developed alternatives but ideally they should be phased out in favor of a market based tax system.

Obviously this task should be handled from many angles with a fluid array of solutions and those you have suggested will be cost effective to a certain degree, evictions will still ultimately have to take place however, alongside incentive based policies like free rides back across the border of course, and this will mean the police will need new special powers.
