Is it feasible ?

I won't get a filter per lens

Should be.

You could do with a step-down ring but you'd probably have to say goodbye to using the hood in such an arrangement.

The cheap Chineses adapter rings are fine at around 1-2 euros each inc. postage, get a set they're just so useful with good quality filters costing  so much for each lens, you'll do fine!

...but you'd probably definitely have to say goodbye to the lenshood....

The important is the optical quality.

Just ordered B+W polarizer, will be using on

24-105f4 IS, 17-55f2.8 IS (both 77mm)

15-85 and tokina 24-200 (72mm)

10-18(67mm)

for the 50f1.4 and 100mm macro and 70-300IS I already have a cheap polarizer, with overlapping alternatives and focal lengths I don't feel I would use a polarizer on them anyway

I already ordered a 77-72 stepdown ring, do you think a polarizer makes sense at 10mm ?

No.
