Do you mean a mix of printing money and taxes -- e.g., just outright abandoning the idea of independent central banking and separation of monetary policy from fiscal policy and using a mix of directly printing money and regular taxation to fund the benefit?

If so, I think that's a poorly conceived idea that, in the best case, has no advantages from running monetary policy independently with similar priorities to those that drive it in principle now (managing inflation and unemployment), while paying UBI out of general government funds while funding the government through a mix of taxation and debt as now.
