Eb vs D neck

[Paddy Morris]

I have 2 basses I use regularly.  One is a laminate Chinese slapper.  The other is a carved Westbury (also Chinese) which I use for jazz and swing.  But they have different neck scales.  So swapping between them plays havoc with the intonation, particularly in the upper registers and thumb position.

 

One solution suggested by a luthier is to carve a new nut to shorten the scale of the laminate bass and make both basses the same.  This sounds expensive, and I would be spending money on the inferior instrument. 

 

I have read that when players hire a bass with a scale they aren't used to, they will slip the bridge slightly off the f-hole notches to tweak the scale.  Do you think that might work for me?  I would doing it on the laminate, which presumably has a more robust top the carved one.  Tone wise it's not really an issue, because the laminate is kept really heavily damped down to control feedback.
