Basically yes, though I'm rather sure your soldering and wiring skills won't result in a proper USB2.0 compatible signal path either. Anyway you're probably relatively safe, as each USB connector, on mating, has a make-GND-first property, so unless you plug in open-ended USB cables (I.E. cable not connected at other end when plugging it to N900) you probably can't create a critical ESD event on datalines by using the D+/- testpads for alternative connection of a mounted USB receptacle - only if you properly route the wires from receptacle to testpads away from case and flat on PCB surface all the time.

I'd rather suggest you send photos, I give advice for a better way to connect D+/-, and you find somebody skilled enough to do the soldering without breaking components again.

cheers
