I am no HAl expert but Yes it's possible.
But there is little motivation to do it.
HAL requires the realtime kernel to control any real device so you must untangle that from the make file too.
Why would you want to?
By the way classicladder is actually a separate project. The version EMC uses 7.124 and the most current is 9.0 I think.
The parent project does not use HAL to communicate, it drives the parallel port directly or can use modbus
