Moving tuplet brackets

[Paul Hodges]

I am at present being asked to put a lot of tuplet brackets on the same 
side of the staff (above) as slurs, and this is leading to a lot of 
collisions.  I could deal with them individually (a lot of work), but is 
there something I can do to to force tuplet brackets away from slurs 
(outside them) globally?  I've not been able to find anything that suits 
yet.

This is probably complicated by the fact that I am already using code to 
force the brackets horizontal (code by Harm I think, from a mail about 
ten years ago).

Here is a sample of what I currently have:
and here is a sample of another piece as the publisher wants it:
