No, two 8 inch flex returns would not be near enough for any system.
Yes it is ok to use flex for a return and the size depends on your system. Out here, I prefer 14" for two ton, 16" for 2.5 and 3 ton and 18" for 3.5 and 4 ton and so on.
And remember, two 8" returns would not equal 16."
Need to list the equipment size for further help.
