Service ref as channel ID?

Hello. Is it possible to use E2 style service refs <1:0:19:1644:42c:1:c00000:0:0:0:> as channel ID's?
This would make automatic mapping easy for those of us using satellite where multiple different channels can have the same name.
Some providers have a map of which channel ID goes to which service ref. Individuals could just replace the IDs with service refs for use in TVH.
