3.5 Business content on 3.1 system possible?

Hi

In general I wonder if it is possible to install Business content released in 3.5.2 addon on a 3.1 system (BI_cont 330)

In specific we would like to use the 2LIS_46_GTM extractors etc for Global Trade management without upgrading the exsisting BW environment.
