I think you can get away without power doors if you have someone supervising each one.
There's the visual announcements to consider too. Perhaps a set of pre-printed notices with someone to hold up the right ones at the right times? Or even a whiteboard?
In the original IET documents, it suggested that bringing Mk3s up to regs only required an accessible toilet and compliant interior door handles. I wonder of fitting internal handles would suffice for the Mk2 sets.
A PIS could probably be fitted, but the issue with most of these things is time and cist
