RE: Cherrymax removal
Apart from that you could get a hammer and sharp chisel, knock the head off and then with a small punch, pop the tail out. Of course blind rivets are used where you cant get access to, so unless you can get something in to remove the left-overs then you will have some bits rattling around.

However, if memory serves, then i think its impossible to remove without any of the aforementioned methods. If there were another method (i.e better) then i'm sure it would be standard practice for use.
One thing you could do is to get yourself some thin gauge titanium/steel and drill a hole into it (slightly bigger than the rivet head), then overlay your strip onto the rivet and you can use it as a sacrificial wear plate, just incase the grinder slips. Make as many strips as you have rivet head diameters.

These things have a locked in steel stem.Worst shop practice I can imagine. It sometime takes two men & a bulldog to drive out the stem even after the collar is removed.

Light structure - carefully drill centre of stem with no 40 cobalt drill approx 0.050" deep. Then with no 30 drill, drill out lock ring to depth of head. 1/8 punch will pop off the head with a flick of the wrist.
Heavy structure - specially ground punch, short tip 1/16 diameter will punch down the stem below the lockring enabling the ring to be flicked out. Then with no 30 drill, drill out lock ring to depth of head. 1/8 punch will pop off the head with a flick of the wrist.
These both assume a 1/8 fastener. For larger fasteners use the corresponding larger drill. Be careful when you pilot drill as sometimes a drill will simply push the stem through once lockring is compromised. You will find this technique usually works for most lockring type blind fasteners such as Huckclinch, Huck & Cherry blind bolts.
