Security can be difficult if you're not leaving from terminals D/E and try to access them, but I've heard it's possible.
AFAIK, MIA no longer uses Concourse E - airlines remaining in E are Aeromexico, Alaska, Cayman and WestJet. The two operating Admirals clubs are both in the D Concourse: the first is near Gate D30, the second near Gate D15.
Generally speaking, the "finger" design of the Concourses doesn't permit for airside movement between the different Concourses (an exception is the airside walkway between D and E, a leftover from the recent past when AA used).
