You cant just bore some hole on the rear spindle, the lower mount is a complete different type, you'd need either coilovers with rear Z32 lower mounts, or Z32 rear shocks, not too sure on the Q45 dimensions, but there might be a small possibility that they could be used.
But yeah the rear spindle has nothing to do with the hub, the rear spindles are the same as far as bolting hubs to them, however you cannot use the Q45 rear hubs with Schassis/j30/z32NA axles, they will not work.
Front Q45's im pretty certain will not work like that either, the J30's however can be done, if the Q45 hubs happen to be the same style, which im quite certain they arent, then you can proceed with them, but its not as simple as press bearing out, press in done, you need to have them pressed out, a new groove for the retaining ring machined in a new location, and then the new bearings pressed into the hubs after. Figure about $110 for new bearings, $50-60 for machine work, and a set of J30 hubs.
Sorry to foil your plans, but thats the actual facts of what you are looking to do.
