Hi, Saxray! That's a great question. If you're recording rehearsals and practice sessions and want better sound, plugging a stereo pair of small-diaphragm condensers into your Zoom recorder is definitely a good idea. I don't think your Shure will be sensitive enough for miking a whole group, you'll probably want condensers. Dynamic mics like your Shure are better for close-miking since they're passive. (Keep in mind, in addition to the mics, you'll need to get enough stands and cables to set them up, if you don't already have them.)
I, personally, would stay away from modern AKG stuff. There are affordable alternatives these days with much better quality control. While I haven't personally used them, the Line Audio CM4 gets REALLY great reviews, is remarkably affordable, and is hand-made in Sweden. You can get a pair of them for under three hundred bucks, which is a bargain for quality mics. People also like the SE8 and, if you can budget for some better gear, Beyerdynamic MC930 -- that last one is a really good quality German-made mic with a strong pedigree and high quality, but not quite as expensive as other German industry standards like Neumann or Schoeps.
I recently wrote a lengthy blog post about how musicians can step up their home recording game, give it a read if you're curious in case you find it useful! Good luck on your quest.
