wouldn't using Kerberos 5 be the way you would want to go?
getting rid of Kerberos 4 is a good thing; and if your KDC support 
Kerberos 5 why wouldn't you use it?

MIT Kerberos 5 1.3.3 does support RC4-HMAC and if the client sends that 
enctype in
a TGS_REQ the KDC will reply with it.   You need to make sure though 
that the Kerberos
principal(s) for the afs cell(s) served by your KDC only have the 
des-cbc-crc enctype
associated with them.

What is used by the client for its TGT does not matter as long as the 
service ticket uses
DES-CBC-CRC:AFS
