Shared sump question

[ElGuappo]

i am going to be building a 2 tank system with a shared sump and am wondering if a single return pump feeding both tanks would work. or is it a hazard should one tanks overflow clog? both tanks will have an emergency overflow as well.

just wondering if it would be better to run a smaller return for each tank instead of a larger return "t"'d to both tanks.

Any input would help

Thanks.

Edit: guess i should add both tanks are going to be approx 26 G each with a sump about 40 to 50 gallons.
