technically yes you can do that but without a fill tank you will need to fill each bag depending on how you plumb it all. this is also assuming your bags are not leaking, when most factory air suspension bags do at this time and age! what is broken on your air suspension now?
the tubing on factory air suspension is 1/4" hardline, like the brakelines, with flare fittings. you will need to know how to work with hardlines, cut and/or tap and flare them, in order for your idea to work.
