I don't object to -spanglis.  

I would not mind a system to encode other combinations, however I don't like the idea of a system as complex as some of the proposals for -t-, and I (& Microsoft, but we're individuals here) are not at all keen on overloading -t- to describe code switching.

I think that there's no harm in registering -spanglis (or other possible requests like -hinglish) even if a more general solution for that concept is agreed upon in the future.
