Only because Sportsguy mentioned not wanting to pay that much for a full oil change at ~$17 for 2 liters of 300V. With mixing them, you might still get the benefits of both oils at a cheaper cost. The superior ester base stocks of 300V, with the added detergent levels and lower cost of 8100. There are actually guys at bobistheoilguy that regularly mix oils to achieve a certain viscosity or additive blend.
I guess the caveat of mixing oils is you really don't know how the new package will work together. Some additives actually compete with each other such as detergents trying to clean away layers of anti-wear additives. Anything regarding Motul, you can just look up their phone number and give them a call.
This is why it's always a good idea to do a few uoa's
with the TBN. If your wear metals are low, you have a decent TBN, and flashpoint is good, there's no reason not to run an oil to 7,500 miles.
