  I've used DOT 3 and 5 with success, including switching from 3 to 5 with a complete flushing of the system.  Avoid 5606 as that is what swells the bladders.
Likewise,  I was able to remove a wheel from a stuck brake with a swollen bladder due to the use of 5606 with the appropriate "persuader" tool.  Replaced the bladders, flushed the system and used DOT 5 and all was well.  I can't recall if we replaced the shoes too.

I just went thru this on a customer's PT-23. It's not as bad as you think. Yes there is someone out there buying up every ounce of Hayes wheel and brake parts. Soon we'll probably see a new dealer's sign selling Hayes parts for a lot more than we used to pay. My customer did manage to find a new old stock expander tube, set of shoes and a drum. Got him back on the road. Part of the problem is the owner's choice of brake fluid. Switching back and forth from petroleum base and auto type 3/4 or silicon 5 doesn't help the expander tube at all. If there has been a lot of fluid choices made in your brake's past then do your own research and choose the best for your needs and then flush the entire system with the correct chemicals and methods. Replace all rubber parts expose to assorted fluids.
As for removal I simply choose a heavy 4x4 or 6x6 and ram the wheel off the drum.
For the 310 style brakes and wheels there are a few folks out there using them and the recent rewrite on Part 23, improvements to aging aircraft, you should not have a hard time peddling a Field Approval thru a FSDO.
Red lines are ok. A wee bit of overkill sometimes but they work fine. I've only installed them on T-6's and Stearmans.
