Glad you are loving it thus far, it really is a wonderful beast and as you say with the pick ups - enough, depth, clarity, beef to be used across many scenarios and not too high output you struggle with them and pedals/preamps etc.
Only caution about swapping out the Geddy pick ups would be would you not want a slightly different flavour?
I am all for mods and changing, but each bass having a little nod of its own.
Plus - have we seen pics yet?!
