     Uh, "man gpt":

     gpt migrate [-fs] device ...
             The migrate command allows the user to migrate an MBR-based disk
             partitioning into a GPT-based partitioning.

and if it happens to be a bootable disk:

     gpt biosboot [-c bootcode] [-i index] device ...
             The biosboot command allows the user to configure the partition
             that contains the primary bootstrap program, used during boot(8).

     Not easily.  You could access the space via the raw partition
since that doesn't use the disklabel size, but you couldn't put a
file system there.
