Can two people sell separate properties and 1031 exchange into one w/LLC parnership?

[Chase Leibfritz]

Here is the quick question: My mother in law is looking to sell bare land in Idaho that is owned outright. It is expected to bring 750k. I have a property that I am selling in Utah at 630k. Is it possible for us to form an LLC and 1031 these into one 1.5 million dollar property in Oregon so long as we abide by the timing guidelines concerning the exchange. TIA
