I tried the second method that compress collections file by dropstuff in mini vmac. But 68K Mac stuff expander can't decompress it.
MacBinary and BinHex can encode one file per time. It would be painful to decode them on another end.

I used stuffit 4.01 from mini vmac. It works for some sit files but not all sit files.

BTW, I have added Ethernet in SE and host an ftp server in modern Mac. But I'm not sure what's your purpose of 040 based mac. Can you explain it more?
