Catherine the Great invited Germans to settle near the Black Sea when she won the territory from the Ottoman Empire. She gave them land in a similar way to the Oklahoma Land Rush: work it and it's yours. The problem came later when Russia changed its mind about being hands-off.
And that's my concern about this plan too. Honduras today is cooperative, but there is no guarantee it will remain that way. In fact, I'm sure it'll end poorly if poor Hondurans see wealthy "Americans" homesteading next door and not paying any taxes.
