sounds like you have the $ and the time for the MR so GO FOR IT!
You'll get to start enjoying the 1K perks sooner, like higher place on the UG lists at the gate, priority boarding, priority security, no fee for using phone reservations etc...
PLUS you'll end up with about 9,000 more RDMs which could always come in handy.
AND it's fun. At least for me it's fun, but if it's not fun for you then maybe don't do it.
