So yes, I was able to get the blanket off in-tact. All I did was pry under it with a firm putty type knife slowly and surely. Maybe even a wide chisel and hammer along the way when encountering resistance. The bottom was a mess as AR used some pretty aggressive adhesion (I think it was some sort of sticky back on the back of the blanket as opposed to glue). But since it was going back on, it wasn't that big of a deal. I simply tried to get the blanket off as much in-tact as possible and I'd say it was about 98%. To re-attach it, I used contact cement on both surfaces and applied a board over it with some weight for the night.
Just need to be very careful with the foam pieces around the tweeter and mid. Those are held on with velcro pads.
I removed the sticker on the plastic piece to get to the screws that held it on. It's a thick plastic sticker so I applied a little heat and once it started coming off, it came off pretty easily. The acoustic blanket is slightly tucked under the plastic piece.
Filled the old grill peg holes once I removed the plastic cups with epoxy to hold a magnet in and then bondo. If going with magnet to magnet contact you gotta make sure you get the magnet installed in the correct direct in both the speaker and grill.
Didn't take a ton of photos but here are a few.
