Just moving the bridge isn't gonna cut it... at least if you want to have any semblance of proper tuning.
Fret spacing is based on the intended scale length, they're at a specific ratio of the total length; this is why bass frets are spaced wider than guitar. With a standard neck, if you lengthen the scale each fret will sound progressively flatter of its intended mark. Basically, you either need a standard baritone neck and move the bridge to wherever it needs to go to make the scale right (probably 28" total), or buy a conversion neck.
The other option is much more difficult, and calculation heavy; move the bridge, keep the neck but defret it and refret it at the right ratios
EDIT - reconsider the Bass VI strings too; Fender's discontinued them, and they'd be long compared to the scale length (extra length required for the floating trem). Of course, you could still use baritone strings, or the Hellcat VI strings from LaBella (they're good AND super cheap i.e. <$5/pk)
