I may not understand what you desire from 13&: Can you elaborate what it is you wish to get from that modifier that you cannot get at present?
If you want programs that do not surprise you in their meaning, 3&: should do the trick. It can be disconcerting that 13&: and 3&: produce different meanings for the same argument, but I find it fitting to think of them as being different things. From that perspective we can't expect them to always have the same results.
