Challenge #4: Dechticaetiativity and Serial Verb Constructions

Could dechticaetiativity be combined with serial verb constructions in a way that creates weird consequences in a language? I've been trying to come up with constructions that combine these features and such consequences, but to little avail. Any ideas?

For those who don't know, dechticaetiativity is like ergativity but for objects and indirect objects, so that the direct object of a monotransitive verb and the indirect of a ditransitive verb are marked the same, and the direct object of a ditransitive verb is marked in the dechticaetiative case.

I bought a book  → I bought a book.acc

I bought you a book → I bought you.acc a book.decht 

Serial verb constructions are constructions where two verbs cooperate to provide more meaning, such as

he take knife cut meat  → he cuts the meat with the knife

As always, suggestions are welcome in the comment field.
