Since you have essentially shut down Exec, I see absolutely nothing wrong
with loading Cop1Lc or Cop2Lc and strobing CopJmp1 or CopJmp2.  (If you are
going to strobe one of the CopJmp registers, you should do so during VBlank,
however.)  You can add a server to the vertical blanking interrupt, or have
the Copper interrupt the 68000 at the appropriate time.

Anyway, it seems ok to me.  I've done my own hardware copper list stuff and
have had no problems with it.
