Reformatting is not indispensable: you can just add a GPT partition
table, carefully setting it up so that the partitions are the same as
before, starting/ending at the same sector numbers.

IIUC, the main benefit of UEFI to the end user is faster boot times.
So if you mostly "suspend to ram" and rarely reboot (and rarely "suspend
to disk"), you likely won't notice much difference.
[ Of course, using GPT comes with its own advantages, e.g. for drives
  larger than 2TB, but it probably won't affect you.  ]
