Yeah I think a merchandise can also be helpful in terms of having a financial support, it can be considered as another backbone for security due to the fact that the product does not expire and can be sold anytime or anywhere. However, I think it would be better to ask the community for pre-orders first before implementing such move to avoid loss of funds.
This way we can see if there is a demand for it while reducing the risk.
P.S. Thanks for the compliment
