Yes, but unlike dmt, you will get an oil. Over time, if left out you would get mescaline carbonate as it salts with the co2 in the air (using seltzer water to salt also works, as its carbonate water). Or at least I've heard that from a few sources. I'm sure mescaline fb is an oil though, and generally harder to work with than a salt.
I've always been interested in doing what you say, evapping some solvent with mescaline fb in it, then scraping it up and adding an appropriate amount of hcl and mixing. Less work than salting, if you don't mind losing solvent. I use orange oil, so its harder to evap and easy to re-use. Would definitely thy this though if i had some toluene.

In a society in which nearly everybody is dominated by somebody else's mind or by a disembodied mind, it becomes increasingly difficult to learn the truth about the activities of governments and corporations, about the quality or value of products, or about the health of one's own place and economy.
In such a society, also, our private economies will depend less upon the private ownership of real, usable property, and more upon property that is institutional and abstract, beyond individual control, such as money, insurance policies, certificates of deposit, stocks, etc. And as our private economies become more abstract, the mutual, free helps and pleasures of family and community life will be supplanted by a kind of displaced citizenship and by commerce with impersonal and self-interested suppliers...
The great enemy of freedom is the alignment of political power with wealth. This alignment destroys the commonwealth - that is, the natural wealth of localities and the local economies of household, neighborhood, and community - and so destroys democracy, of which the commonwealth is the foundation and practical means.” - Wendell Berry
