375, opinion with the drains

[CHIEF_OF_THE_REEF]

I have a 375, it has 2- 1 inch pressure and 2- 1 1/2 inch returns. Can I use 3 of them for the drains and have just one return? will it be enough turnover? I have the Vectra M2 for a return. The reason for only using 1 return would be so i can set up the bean style overflow and have the 1 1 1/2 inch hole for an emergency drain.

Thoughts?
