Rob, we have this environment (31 bit and 64 bit LPARs in the same Sysplex, z/OS 1.4 and DB2 v7). No problem.
You have to take care about Assembler code if you use it for exits/programs/SVC. The new 64 bit instructions are not supported in 31 bit so it's necessary to keep different versions for them.
