That approach is called heterologous prime-boost, and it's likely being tested for the Oxford/AstraZeneca + Pfizer combo and the Oxford/AstraZeneca + Sputnik V combo to try to increase potency (not to increase supply). It's not being tested for the combo of the two mRNA vaccines (Pfizer/BioNTech and Moderna) though.
