Agree with your assessment of the blue brakes, good fluid/pads (I use RSL29) plus I've removed the dust shields (but kept a small part of the bottom to protect ball joints from radiating heat) & have GT3 air scoops, mine last 20min sessions going pretty hard on RE71RS/A052.
I don't think you can easily change the dust boots without unbolting the caliper to provide more access than you'd have with the rotor in the middle. You don't need to remove the caliper completely though, so brake lines don't need to be disconnected. Technically the bolts which hold the caliper to the knuckle are single-use-only.
