Pickup options for a project 5string

[Joebethell]

I'm thinking about a bass I sold a while ago and would like to try and get a similar sort of sound and feel but without the large cost and niggle which made me sell it in the first place. 

The bass in question was a Mike Lull PT5 which sounded amazing but I struggled with the 35" scale. So I'm now thinking of a 34" scale 5string and modifying it to a similar spec: passive TBird style pickups,Maple neck with a finish I have liked for a long time. 

The issue being I am struggling to find suitable pickups for a 5string that are not the lulls (retail is 525ish with surrounds and spacers) Seymour Duncan dont do 5string option and others like mojo are again on the narrow spacing side. 

Anyone got any ideas? 

Thanks
