Can Sage Mode and KCM/BM be active at the same time?

[2nd hokage]

Ok bm is done by equally. Mixing. Host and tailed beast chakra. Sm is done by mixing Yin Yang and nature following this pattern. Sbm would require mixing Yin Yang tailed beast and nature. I see this happening as naruto has Lerner the others already also I belive he will learn more chakra types and be able to make any tota or better becase its the same thing mixing different. Chakras

That wld be awsum coz u can take in as much sage chakra as you have so you have 2X yo norm, with KCM chakra amount doubled so epicness must be shown.
