No. I would be against this 100%. To be a decentralized reserve/treasury asset, we really need liquid tokens. These REIT tokens add another layer of complexity that I don't think Olympus needs. We already have Dai that has done some great work to add RWA, but I don't believe Olympus needs to focus on this exclusively. The reality is these aren't really liquid and require lawyers and governments to really sell. It's just not that liquid or interesting to add to the treasury and I wouldn't accept it considering you really need to trust your counterparties.
I would much rather see starting to add some staked ETH within reason, especially as LP tokens versus OHM as the next major collateral onboarded.
