How to cut costs without a cost cap?

[mathewking21]

looks pretty clear that a budget cap is never going to get agreed , but what regulations could cut costs in small chunks ..relatively speaking

any thoughts on what might be done without altering the character of F1 ?

how about brakes ? if ~I understand correctly the big teams get through a couple of sets of everything each race whereas the poorer teams make do with one

so 40 sets of everything cost ? my guess $1million per season , half that for the small teams then ; we already have a 5 engine rule or is it 4 or......well whatever it is with all the bits and pieces
why not the same for brakes , say 5 sets of everything , easily achievable by the manufacturers for 10thousand Km for a season , slight loss of efficiency , but not much
ok peanuts for the big boys but for the small teams 10 items like that would be serious money AND level the playing field

any ideas ? what would one front wing for the season save ? homologated after pre season testing ?
or a simpler front wing as well ?

you get the drift ...couldn't it work ?
