Noooooope. Part of the whole thing with Free Soilers was keeping farmland open to themselves. This would cause too much friction. Then again, they might just put them in the land most likely to get raided or with the least water.
Actually, as I keep pointing out, by the 1850's and 1860's, most colonization plans did not involve either Africa or the US West but Latin America.
"To many of the earlier colonizationists, whose interest centered on Africa, the plan would not only solve the race problem in the United States but would fulfill a great religious end. American Negroes would serve as Christian missionaries, bringing the gospel to the Dark Continent. In the eyes of Republican colonizationists, however, the Negroes were to be emissaries of a different kind; as black agents of the American Empire, they would help establish the commercial and political hegemony of the United States in Latin America. It is important to remember that during the 1850’s much of the attention of American foreign policy was focused on Central America. That area was a hotbed of international conflict, with the United States and Britain vying for dominance and southern expansionists and filibusters eyeing it as part of a future slave empire. The Blairs argued that the establishment of Negro colonies there would ensure American dominance. Colonization, the elder Blair wrote, would create “rich colonies under our protection, likely in the end, to appropriate the whole region to our use.” 26 Many New York and New England merchants were already interested in commerce with Central America, and Frank Blair made two of his most important speeches on colonization before influential mercantile audiences in Boston and New York. He described the great mineral wealth and trade possibilities of the region, and offered colonization and the Pacific railroad as twin measures which would expand America’s commerce and empire. Central America, Blair declared, “would, in fact, become our India.” 27
"Not only would colonization enable the United States to outflank the British in Central America, but it would also effectively block southern plans to expand the slave system southward. The elder Blair wrote in 1859 that his plan would “build up a free black power, which will counteract the design of making all south of Mason and Dixon’s line to Brazil a slave empire. . . Doolittle drew the analogy between Kansas, where the settlement of white laborers had prevented slavery from establishing a foothold, and Central America, where a free black colony would bar slavery. The peculiar institution and the slave trade, he wrote, could “no more go there than they could go through a wall of fire.” 28
"It was highly ironic that Negroes were considered capable of becoming the agents of American empire in the Caribbean while they were being viewed at the same time as an undesirable population at home. Republicans tried to justify this contradiction by appealing to the widely accepted belief that the white and black races were suited to different climates. 29 Only the blacks could establish American influence in the tropics, because in that climate, as Doolittle put it, “the white race is doomed.” “It is by this race alone,” Frank Blair told his New York audience, “that those regions are to be regenerated, and brought within the circle of civilization.” …"

Lincoln's statement in his famous 1854 Peoria speech that "My first impulse would be to free all the slaves, and send them to Liberia,---to their own native land"
https://www.nps.gov/liho/learn/historyculture/peoriaspeech.htm would seem to link him to the older generation of colonizationists (like Henry Clay, whom Lincoln admired so much) and thus to some extent to justify the OP. But in the first place even in the Peoria speech, Lincoln recognizes the impracticality of the idea: "But a moment's reflection would convince me, that whatever of high hope, (as I think there is) there may be in this, in the long run, its sudden execution is impossible. If they were all landed there in a day, they would all perish in the next ten days; and there are not surplus shipping and surplus money enough in the world to carry them there in many times ten days." Second, that speech after all was in 1854. All the colonization schemes during Lincoln's presidency involved Latin America--and moreover were voluntary.
