Sure you can use it. It will look great until the first time you press on the fabric in the open areas. IE: the open bays between the ribs. Primers by nature have lots of solids and will ''Eggshell'' when you touch it. There are always naysayers that will disagree so the old saying ''There's them that have and them that are gonna'' applies here. You started correctly by using Nitrate dope. Now, switch to Butyrate. Paint, sand, paint, sand, paint, sand, Paint and use the primer on only the solid surfaces. Life will be good, birds will sing and all will be well.
I've used Nelson's paint (not primer) over nitrate dope on open-bay wings with excellent results. Butyrate over nitrate is fine, and I've used that, too, but it's not the only good method. What you say about primer makes sense, but that isn't what the OP is now proposing to use.
