Never mind. I found how to do it. Since VSAM exits are driven after a VSAM operation is performed, it's too late to intercept it. But, if you intercept the ACBs and give VSAM some fakes to play with it works. Of course, this way has it's own challenges with maintaining the ACBs in the correct LE enclave.

As it turns out, I can't intercept VSAM commands, but I can intercept the ACB at open time and redirect the program to my "ACB". The trick is retaining addressability to it if the program does calls that switch LE enclaves.
